Revisiting lagrange relaxation (LR) for processing large-scale mixed integer programming (MIP) problems [PDF]
Lagrangean Relaxation has been successfully applied to process many well known instances of NP-hard Mixed Integer Programming problems. In this paper we present a Lagrangean Relaxation based generic solver for processing Mixed Integer Programming ...

Non-convex mixed-integer nonlinear programming : a survey [PDF]
A wide range of problems arising in practical applications can be formulated as Mixed-Integer Nonlinear Programs (MINLPs). For the case in which the objective and constraint functions are convex, some quite effective exact and heuristic algorithms are ...

Cutting plane methods for general integer programming [PDF]
Integer programming (IP) problems are difficult to solve due to the integer restrictions imposed on them. A technique for solving these problems is the cutting plane method.

Reformulating mixed-integer quadratically constrained quadratic programs [PDF]
It is well known that semidefinite programming (SDP) can be used to derive useful relaxations for a variety of optimisation problems. Moreover, in the particular case of mixed-integer quadratic programs, SDP has been used to reformulate problems, rather ...

Transformation of propositional calculus statements into integer and mixed integer programs: An approach towards automatic reformulation [PDF]
A systematic procedure for transforming a set of logical statements or logical conditions imposed on a model into an Integer Linear Progamming (ILP) formulation Mixed Integer Programming (MIP) formulation is presented. An ILP stated as a system of linear
