APM.LINEAR - APMonitor Option

Global Options | Local Options
 Type: Integer, Input
 Default Value: 0
 Description: 0 - Nonlinear problem
              1 - Linear problem

Linear programming (LP) or mixed integer linear programming (MILP) problems can typically be solved much faster than a comparably sized nonlinear programming problem. The LINEAR option indicates whether the problem is linear. This allows the modeling language to set options in certain nonlinear solvers that improve the efficiency of the solution. All of the solvers built into APMonitor are nonlinear programming (NLP) or mixed-integer nonlinear programming (MINLP) solvers. Some of the solvers have simplifications to handle linear problems as well. This option does not override the choice of solver with SOLVER but does communicate to the solver that the problem has linear structure.
