Abstract

In an earlier work a so-called conflict graph was associated to a given zero-one linear program basically to accumulate information to construct cuts to speed up the solution of the program. Later it was noticed that the conflict graph can be used in fixing values of variables and fathoming partial solutions in enumerative type solvers. In this paper we will show that the conflict graph helps in dividing dividing a zero-one linear program into independent smaller instances and so it opens a way for a parallel solution. Further the conflict graph suggests certain possibilities for preprocessing and simplifying the given zero-one linear program.
