MATLAB mixed integer nonlinear programming

Knitro offers three algorithms for mixed-integer nonlinear programming (MINLP). The first is a nonlinear branch and bound method, the second implements the hybrid Quesada-Grossman method for convex MINLP, and the third implements a mixed-integer Sequential Quadratic Programming (MISQP) method that is able to handle non-relaxable integer variables. Knitro is designed for convex mixed integer programming and is only a heuristic for nonconvex problems. The MINLP code also handles mixed integer. The solver MINLP bb solves large, sparse or dense mixed-integer linear, quadratic and nonlinear programming problems. MINLP implements a branch-and-bound algorithm searching a tree whose nodes correspond to continuous nonlinearly constrained optimization problems. The continuous problems are solved using filterSQP, see below 8 Mixed-Integer Nonlinear Programming In minlp_prob there are 14 mixed-integer nonlinear programming test problems with sizes to nearly 50 variables and nearly 50 constraints. In order to define problem number n and solve it execute the following in Matlab: Prob = probInit('minlp_prob',n); Result = tomRun('',Prob)

g(x) ≤ 0 (inequality constraint) h(x) = 0 (equality constraint) xi ∈ Z (integer constraint) This is the most general form of integer programming and is called a mixed-integer nonlinear program (MINLP). Many problems can be formulated with only linear objectives and constraints Mixed Integer Nonlinear Program (MINLP) Problem Definition. An MINLP has the following form: Where f is a scalar function containing the nonlinear objective function, which is subject to the following constraints: Linear Inequalities* A is a m x n sparse matrix, b is a m x 1 vector. Linear Equalities* A eq is a k x n sparse matrix, b eq is a k x 1 vector. Decision Variable Bounds. l b and u b. Integer programming algorithms can be implemented in software such as MATLAB ®.Solving MILPs typically requires using a combination of techniques to narrow the solution space, find integer-feasible solutions, and discard portions of the solution space that do not contain better integer-feasible solutions To write these constraints in the form A x ≤ b, multiply the second inequality by -1: -3 x1 + 2 x2 ≤ -5. You can try to include the equality constraint using A = [3,-2;-3,2] and b = [5;-5]. Be aware that this procedure can fail; ga has difficulty with simultaneous integer and equality constraints

The objective function f is linear however there is a second. Since methods for solving integer programs include approaches like relaxing the integer variables to continuous variables, then solving using a branch-and-bound (or branch-and-cut, or other) scheme, from an implementation perspective, implementing an integer programming solver frequently means mixed-integer programs can also be solved. $\endgroup$ - Geoff Oxberry Jun 18 '15 at 22:1
