Tiivistelmä: | The linearization technique of Glover, which seems to be the most efficient one appearing in the literature, requires the addition of n new continuous variables (unconstrained in sign) and 4n new linear constraints to equivalently represent a 0-1 "quadratic" integer problem with n variables. Shown is that it is still possible to improve such a procedure. In fact, the number of new continuous variables can be kept at n (but constrained in sign) while further reducing the number of new linear constraints from 4n to 2n. The analytical superiority of the proposed method is also supported by a computational experiment conducted on a small scale. |
