lpi.h File Reference Detailed Descriptioninterface methods for specific LP solvers This file specifies a generic LP solver interface used by SCIP to create, modify, and solve linear programs of the form min/max obj * x lhs <= A * x <= rhs lb <= x <= ub and query information about the solution. Although it includes a few SCIP header files, e.g., because it uses SCIP's return codes, it can be used independently of any SCIP instance. The basis status for (column) variables are as follows:
The basis status for (row) slack variables are:
If the solvers use their status differently, the have to be corrected. In the methods accessing information about the (inverse of the) basis matrix, the interface assumes the following column-oriented format: slack variables of rows have coefficient +1 and the basis matrix is a regular m times m submatrix of (A,I), where m is the number of rows and I is the identity matrix. This means that if, internally, the LP solver uses coefficients -1 for some of the slack variables, then rows associated with slacks variables whose coefficient is -1 should be negated in order to return the result in terms of the LP interface definition.

gets pointer for LP solver - use only with great care The behavior of this function depends on the solver and its use is therefore only recommended if you really know what you are doing. In general, it returns a pointer to the LP solver object. gets pointer for LP solver - use only with great care gets pointer for LP solver - use only with great care Here we return the pointer to the LP environment. gets pointer for LP solver - use only with great care Here we return the pointer to the model.
