WebMar 10, 2024 · Download PDF Abstract: We investigate the theoretical complexity of branch-and-bound (BB) and cutting plane (CP) algorithms for mixed-integer optimization. In particular, we study the relative efficiency of BB and CP, when both are based on the same family of disjunctions. We extend a result of Dash to the nonlinear setting which … WebNP-complete [11, Chap. 15]. It is highly unlikely that there exists a polynomial-time algorithm that uses branch-and-cut methods to solve integer programs. In fact, some classes of branch-and-bound algorithms have been shown to have worst-case exponential time complexity for solving 0{1 integer programs.
