sos.m

这个例子创建了一个非常简单的特殊排序集(sos) %模型。狗万app足彩该模型由3个连续变量、无线性%约束和一对1型SOS约束组成。模型。Ub = [1 1 2];模型。Obj = [2 1 1];模型。modelsense =“Max”;模型。一个=稀疏(1、3); model.rhs = 0; model.sense = '='; % Add first SOS: x1 = 0 or x2 = 0 model.sos(1).type = 1; model.sos(1).index = [1 2]; model.sos(1).weight = [1 2]; % Add second SOS: x1 = 0 or x3 = 0 model.sos(2).type = 1; model.sos(2).index = [1 3]; model.sos(2).weight = [1 2]; % Write model to file gurobi_write(model, 'sos.lp'); result = gurobi(model); for i=1:3 fprintf('x%d %e\n', i, result.x(i)) end fprintf('Obj: %e\n', result.objval); end
