Approximability of NP-Optimization Problems,ndicates in a pictorial way why an a priori seemingly theoretical concept as the notion of NP-completeness has been so successful. Till today, the first attempt of every student, researcher, algorithm designer with a new problem for which he can’t find a polynomial-time algorithm immediately is to try proving that it is NP-complete.

Pattern Inference under many Guises,p of identical objects. If the objects are not identical but almost (there are just a very limited number of well-characterized differences between them), one could perhaps adjust the operation to a smaller number of steps than starting from scratch for each object among the group of almost identical ones.

On the coloration of perfect graphs, edge . of G has . ≠ .. If . we say that . has color .. Those sets c.(T) (. = 1,..., .) that are not empty are called the . of the coloring c. Each color class is clearly a stable set (i.e., a subset of vertices with no edge between any two of them), hence we will frequently view a coloring as a par
