          Abstract

          Two famous hard optimization problems are colouring the  vertices
          of  a  graph  and  finding  the largest clique in a graph.  These
          problems are known to be  NP-complete  for  general  graphs.   In
          1960, Claude Berge defined the class of perfect graphs.  Both the
          colouring and clique problems can be solved in polynomial time on
          these  graphs.  We  discuss algorithms to solve these problems on
          some special classes of perfect graphs.  We discuss  applications
          of these algorithms in scheduling, micro-code generation and com-
          putational geometry.
