He got his PhD from Yale approximately in 83. If anyone has a copy available or knows of Billy's whereabouts (possibly BBN?) please let me know (including netmail address). Thanks. --Rolf Pfeifer ------------------------------ Date: 7 Nov 85 13:40:15 GMT From: Bob Stine <stine@edn-vax.arpa> Subject: Intensional Contents 'whois zalta' fails, so I'll direct this request to the net. Can anyone give me pointers to Edward Zalta's work on the "intentional contents of mental states about fictions?" In AIList Digest V3 #163, it was announced that Dr. Zalta would be giving a lecture in Berkeley on that topic. Would one use Golden Hill LISP to code assertion's about Meinong's Golden Mountain? - Bob Stine ------------------------------ Date: Thu, 7 Nov 85 16:03 From: at GEC Research <YE15%mrca.co.uk@ucl-cs.arpa> Subject: Validation of Knowledge Based Systems I am interested in carrying out some work on the validation of real-time Knowledge Based Systems and would appreciate some help in getting started. If anyone has any information they can send me on this topic, in particular, significant references or current projects it would be a great help. Thanks.

His aim was to use diagrams to aid in proving geometrical theorems. If I remember correctly, he succeeded in that his program was able to prove several theorems in geometry. The work is reported in one of the issues of the IBM research journal in 1960. Gelernter has since escaped to Biophysics as an occupation (!). ------------------------------ Date: Thu 7 Nov 85 10:14:32-CST From: David Throop <AI.THROOP@R20.UTEXAS.EDU> Subject: RE: RSA encryption > ... I will also discuss (the Boyer Moore theorem prover's) proof of the invertiblity of the RSA public key encryption algorithm ... > Has RSA been broken? I thought it was NP complete. Can you give a reference? ====================== No, it has not been broken. But it has been proven invertible. That is, consider an (input) message encrypted with a public key and an (output) string produced by decrypting the (encrypted) message using a private key. The Boyer Moore theorem prover has rigorously proven that, given any possible input, the output will be identical to it. As Dr Moore said in last night's talk, what you would like to prove is that no one can solve the encrypted message with only the public key. But that's not provable, because the problem IS solvable. Its just very hard. NP hard, in fact. What you would really like to prove are some things about the properties of NP problems. You will certainly hear about it if anybody around here proves any such thing. ------------------------------ Date: 05 Nov 85 2115 PST From: John Craig <JJC@SU-AI.ARPA> Subject: Typed languages and Lisp [Forwarded from the Stanford bboard by Laws@SRI-AI. This is part of an ongoing discussion of strong typing.] Chris Goad (Stanford CS grad) developed a language originally called SIL, now called RISE which is essentially a typing system added to Lisp, but with a no-type type so that one can get around typing as one desires. The main reasons for adding typing are: 1) faster code development (type checker finds bugs) 2) the compiler can use type information to generate more efficient object code (for example, less or no garbage collection pauses when running compiled code) RISE is in use at Silma Inc (Los Altos) and forms the user interface for their product, RoboCam. It seems to me like you get the best of lisp and typed worlds, and efficient code generated also. Its pretty fun, too.

Big poster, bright colors (thankfully not as garish as certain other announcements), lots of pictures, little information. By contrast, announcements for ACM conferences stick to the salient details and do it on the standard size sheet of paper, although they do get radical for the national conference and put in a little icon... If AAAI can't seem to escape the need for hype, why should anyone assume there's actually something real in AI? stan shebs ------------------------------ Date: Sat 2 Nov 85 08:20:07-PST From: the tty of Geoffrey S. Goodfellow <Geoff@SRI-CSL.ARPA> Subject: The Ultimate Hype: Mail Order "AI"! In the interest of keeping the AI Research Community-At-Large informed of just how out of hand AI Hype is, I offer, for your consideration the following travesty (if you will) from the latest edition of the JS&A "Products that THINK #16" yuppy catalog. Both pieces are rather lengthy, but in order to appreciate the fullness of egregiousness they espouse to our public about "ARTIFICIAL INTELLIGENCE" (emphasis added here as well as below), I have included them in toto. [I have taken the liberty of cutting Geoff's 17K-char message by about half. -- KIL] -0- -0- -0- -0- Back Cover: (full page) MARKET VICTIM I used to be a sucker for the stock market. I'd get a tip from a friend, I'd invest on a hunch or a broker would offer me some advice and off I'd go. On the average, I never made any money. So I dropped out of the market until I met Hal and Bill. Hal was one of the most astute market advisors I have ever met. At first, I didn't trust Hal. Despite his good credentials and a well-documented three-year track record, was still suspicious. [...] It took the incredible accuracy of Hal and Bill to finally get me back into the market. Hal had selected 14 stocks out of the 1500 on the New York Stock Exchange that he felt would really take off. A few I had never heard of. Bill advised me to sell some of my stocks in the nick of time so the net results were 13 out of 14 winners with a few stocks giving me a return of greater than 30% in just a four-month period. [...] Hal and Bill are ARTIFICIAL INTELLIGENCE computer programs--two independent programs that perform what no other advisor or market expert has been able to perform in the history of investing. I can now sit at my Visual Computer (see page 10), insert both Hal and Bill into my disk drive, and be told by this intelligent program what stocks on the New York Stock Exchange to buy and when to sell them. [Runs on IBM compatibles with 256K memory.] Hal gives his advice on the long range--usually his advice is good between a three to nine month period after he makes his decisions. Once that happens, I then follow Bill very closely because he tells me when to close that position. If I want to know when to sell, I let Bill tell me by first downloading the last 36 days of stock market activity from the Dow Jones News Retrieval service with the help of my telephone modem. The program does this automatically--all I do is press a few buttons. Then Bill takes that information and advises me. Between both programs the accuracy will amaze you. But that's not all. [...] The entire program is called Halographix. [...] The program features all the tools you need to analyze evaluate and record your transactions. It has automatic log-on features that access the Dow Jones News Retrieval service and download information on any stock you've selected for your portfolio. Each disk is valid for only four months. You pay only $199 for the program (that's roughly $25 for each of the two independent programs per month), and purchasing the disk entitles you to renew the disk every four months thereafter for the same $199 per disk. Obviously, if the program doesn't make you plenty of money, you don't renew. But for the few who have participated, practically all of them have enthusiastically remained with us. Our guarantee of satisfaction is very compelling. If, after the four months, you are not satisfied with the program or have not seen it pay for itself many times over, please return it and get a full refund of your $199 investment. You can't lose. To order, simply send your check, money order or credit card number to me personally, Joseph Sugarman, President, JS&A Group, Inc., One JS&A Plaza, Northbrook, Illinois 60062. If for some reason, we sell out our subscription for this issue, I will promptly refund your money and keep you on our list for our next release. But I urge you to act quickly. I also urge you to read the article on page 20 entitled "Million Dollar Phone." In that article, I give you an idea of the nature of ARTIFICIAL INTELLIGENCE and the philosophy of how the program works to accurately predict market movement. ARTIFICIAL INTELLIGENCE, the tremendous number-crunching power of your own personal computer and the skills of a computer programmer have produced a personal friend for the small investor. You can now compete with the big institutions on Wall Street with advice more accurate, personal and more astute than their huge network of advisors and computers. Join with me in this novel program and enjoy the wealth of information Halographix provides to guide you to success in your investment activity with the New York Stock Exchange stocks. Halographix (6082N 6.00)..........$199 -0- -0- -0- -0- Page 20/21: MILLION DOLLAR TELEPHONES What you are about to read may sound like a get-rich-quick scheme. And indeed it may be. [...] For the past year, I have been working with a computer genius who has developed a program that, when run on a powerful computer, can predict the movement of the Dow Jones Industrial Average. In our first year of testing this program, our computer generated ten signals. Nine were accurate with the Dow making the forecasted moves within twelve trading days. To my knowledge, there has not been an advisor, a market expert or another computer program that has been as accurate. Two years ago a new form of option trading was introduced to investors. Called OEX options, the concept gave investors a way to speculate on the movement of the Standard and Poor's market index. This market index is very easy to follow because it runs almost parallel to the Dow Jones Industrial Average. If you were right on the movement of the overall market, you could possibly double or triple your investment within a few short weeks. If you were wrong, all you could lost was your initial investment and no more. Another popular feature of the option program is the tax treatment. 60% of all your gains are treated as capital gains and 40% as ordinary income or about a 32% effective tax rate. [...] I have formed a club called, "Dial-An-Option," which will offer information on the Dow Jones Industrial Average. First you sign up with JS&A as a member, which costs you only $25. Then, at no extra charge, we provide you with information on one major market signal. Next, sit back, relax and watch what happens to the Dow over the next two weeks following the signal. [....] Our advice will be sent via an overnight delivery service so you'll get the first market signal well enough in advance to act quickly. The signal must make money for you and double or triple your investment or you can drop out of our Dial-An-Option club and we'll refund your entire membership fee. Or don't take the chance and just follow the market and see what you would have made had you invested on our advice. [...] Why does our computer program work so effectively? What does it do to predict the Dow so accurately? If you'll take just a moment, I will explain. ARTIFICIAL INTELLIGENCE The big buzzword in software today is, "ARTIFICIAL INTELLIGENCE," or a special level of reasoning applied to a computer program. The reasoning involves looking at hundreds of factors at once and then comparing those factors to previously programmed responses and then drawing a conclusion. Our brains operate on a similar basis. We are programmed with patterns based on previous experiences or programming. When we have to make a decision based on new data, we lay that new data onto previous data and then draw our conclusions. With the number-crunching capabilities of a powerful computer and an ARTIFICIAL INTELLIGENCE software program, our computer can sense market movement, movement within an industry group and even movement (accumulation or distribution) within a specific stock. If then computes the major 30-day trend, and interprets the fluctuations in trading and valuation levels to determine the one-to-five day pattern within the major trend. [...] Our computer has the ability to first sense the changes and trends in the market before they become obvious and then, with the minimal amount of information, develop a comparable pattern and make a conclusion--an ideal system for predicting the movement of the Dow Jones averages. [...] No program or system can guarantee future profit or success. If we are not correct on any of our calls (remember, so far we've been right on nine out of ten calls), then you'll receive a refund of the fee--something that no other advisory service that we know of provides. Obviously we can't guarantee any loss that may result from our advice but we urge you never to invest more than you're willing to lose. [...] Thanks to a powerful computer, ARTIFICIAL INTELLIGENCE, and a brilliant program, we can no do this analytical work on a computer with greater accuracy than even the most astute analyst or the most powerful institution. I urge you to join our club and experience the power of our computer and its new program designed to earn you bigger returns than you've ever dreamt possible--and all in a very short period of time. We've given the small investor the tool to compete with the big institutions and enjoy the potential profits offered every day in the market place. Join our club, today.
