SCHUTZ, G.  and  PIRES, F. M.. A genetic based algorithm for the quadratic 0-1 problem. Inv. Op. [online]. 2003, vol.23, n.1, pp.71-84. ISSN 0874-5161.

In this work we present an algorithm to the unrestricted binary quadratic program. This approach combines genetic operators with greedy and heuristic procedures. We started from a genetic based algorithm and replaced the random mutation by a greedy procedure based on each variable contribution to the objective function. We also introduced in the genetic population an individual obtained by a heuristic that finds a local star minimum point. Computational experience with a set of test-problems, known from literature, is reported and analysed. Our results are quite promising.
