symphony Solves a mixed integer linear programming constrained optimization problem. Calling Sequence xopt = symphony(nbVar,nbCon,c,isInt,lb,ub,A,conLB,conUB) xopt = symphony(nbVar,nbCon,c,isInt,lb,ub,A,conLB,conUB,objSense) xopt = symphony(nbVar,nbCon,c,isInt,lb,ub,A,conLB,conUB,objSense,options) [xopt,fopt,status,output] = symphony( ... ) Parameters nbVar : a double, number of variables. nbCon : a double, number of constraints. c : a vector of double, represents coefficients of the variables in the objective. isInt : a vector of boolean, represents wether a variable is constrained to be an integer. lb : a vector of double, represents lower bounds of the variables. ub : a vector of double, represents upper bounds of the variables. A : a matrix of double, represents matrix representing the constraint matrix. conLB : a vector of double, represents lower bounds of the constraints. conUB : a vector of double, represents upper bounds of the constraints objSense : The sense (maximization/minimization) of the objective. Use 1(sym_minimize ) or -1 (sym_maximize) here. options : a list containing the the parameters to be set. xopt : a vector of double, the computed solution of the optimization problem. fopt : a double, the function value at x. status : status flag returned from symphony. 227 is optimal, 228 is Time limit exceeded, 230 is iteration limit exceeded. output : The output data structure contains detailed information about the optimization process. This version only contains number of iterations Description Search the minimum or maximum of a constrained mixed integer linear programming optimization problem specified by : \begin{eqnarray} &\mbox{min}_{x} & f^T⋅x \\ & \text{subject to} & conLB \leq A⋅x \leq conUB \\ & & lb \leq x \leq ub \\ & & x_i \in \!\, \mathbb{Z}, i \in \!\, I \end{eqnarray} The routine calls SYMPHONY written in C by gateway files for the actual computation.
