LpDefine

Defines a linear programming problem.

Full set of Parameters

LpDefine supports many optional parameters. The full set of parameters are as follows:

• Vars : Index
• Constraints : Index
• objCoef : Numeric all[Vars]
• Lhs : numeric all[Vars,Constraints]
• Rhs : numeric all[Constraints]
• Sense : optional Textual[Constraints]

One of: '<', '>' or '='

• Maximize : optional Boolean

True for maximization problems, false (default) for minimization.

• Lb : optional Numeric[Vars]
• Ub : optional Numeric[Vars]
• CType : optional Textual[Vars]
  • 'C' : Continuous (real-valued)
  • 'I' : Integer-valued
  • 'B' : Binary (0/1) valued
• Group : optional number all[Vars]
• Engine : optional text

Used to select a third-party (non-default) solver engine. Use SolverInfo("AvailEngines") to get a list of installed engines.

• Parameter : optional Text
• Setting : optional numeric

Parameter and Setting are used together to change a search-control parameter from its default value. To set multiple parameters, ensure that Parameter and Setting contain a common index. For a list of parameters supported by a given engine, use SolverInfo("DefaultSettings",engine:engineName).
