As the output of a working conference held in that period, on a fast advancing field, this is about all one can reasonably expect. It is regrettable that Reilly was misled by the title, without its subtitle, into believing that it was more than this. One can also regret the high price set by the publisher. Presumably though, if the book is as unmarked as Reilly indicates, it can be returned for full refund. It seems that Reilly is somewhat put off by the inter- and self-references of the editors. (Incidently, one wonders why he was not likewise put off by other articles such as the one by Goldberg-- which he did find useful-- which has 9 self-references, and 8 to the pioneering work of Holland). Speaking for myself, I can say that one main reason that I put in citations to previous work, my own or others, is when the referenced works are needed to support the flow of ideas (generally space precludes reproducing such background in detail). It also happens that the editors (Elzas, Oren and myself) were co-operating closely at the time, sharing each others ideas-- with attribution. What may appear as "backslapping" or self-agrandizement to some, might help others to locate the background needed to make the writing understandable. The fact that Oren makes 66 citations in total should also put the self-references in context. Finally, I am appreciative that Reilly took the time to write the review. From my own, no doubt biased, perspective, I would emphasize another point: the book is one of a continuing series of efforts towards a more methodological approach to simulation. The field has a wide and diverse application community. Like software construction, it needs a rigorous engineering foundation. The book brings together, and organizes, some 28 articles relevant to this-- as yet unrealized-- goal. Researchers will, one may hope, be stimulated by some of its nascent ideas. Others must await a more definitive treatise once all the results are in. B.P.

Current and future decision making tools will rely heavily on the ability to reason with sophisticated models that are designed, planned and simulated in real time. This year's conference will be held at the beginning of the Florida AI Research Conference (FLAIRS) at the same location. There is a strong need to integrate the qualitative system structures often found in expert systems, reasoning systems, logic and social science with the quantitative knowledge found in physical science and engineering. Qualitative structures help define high-level (i.e. decision making) control knowledge while quantitative structures define unambiguous operations for well known physical and engineering systems. The interplay between qualitative and quantitative modeling is critical in the area of computer simulation modeling where a variety of models are created to solve different problems and provide different levels of response. Future simulation models will require this multi-facetted approach involving model knowledge bases containing different levels of system abstraction. This conference will serve to bring together researchers interested in using simulation models that have well-integrated qualitative and quantitative components.

Which appeared in : ACM Computer Graphics, Vol: 22, No: 4, Aug 1988 I am particularly interested in : Some more joint restraints. eg. pin joints, screw joints, sliding joints The authors address some of these but I am looking for one equation (in 3 coordinates) for each joint, if at all possible. How joint objects behave when they are not colliding. ie. does the fact that they are joined make a difference to non-impulsive motion. eg. a falling chain which is not attached to a fixed object. I will probably think of some more questions later, but these will do for now. 8^). Thanks in advance, Richard. PS. as I am cross posting this to several groups could you please let me know if this posting is inappropriate for the respective newsgroup. -- /-------------------------------------------+----------------------------------\ | Some of us are poets, some of us are not. | puchm@cutmcvax.cs.curtin.edu.au | + ------------------------------------------+----------------------------------+ | I know nothing, so can hold no opinions for myself or others..... | \-------------------------------------------+----------------------------------/ ------------------------------ END OF SIMULATION DIGEST ************************
