摘要
This paper is to study a mixed-integer second order cone program (MISOCP) problem and its solution algorithm by generalized Benders decomposition. When fixing the integer variables, we solve several subproblems as well as their dual problems and obtain optimal Lagrange multipliers of subproblems which can be used to establish linear valid Benders cuts and reformulate MISOCP as an equivalent mixed-integer linear program (MILP) master problem. Then we construct a generalized Benders algorithm for finding the optimal solution to MISOCP by solving a sequence of MILP relaxations. The algorithm is proved to terminate after a finite number of steps. Numerical results for the MISOCP instance are presented to show the feasibility of the constructed algorithm in solving MISOCP problems.
