GIPALS is 32-bit Windows linear programming software incorporating powerful solver and user-friendly interface to input, import, export and solve linear programs.

GIPALS uses primal-dual interior point method (Mehrotra predictor-corrector) to solve a linear program consists of maximum 500,000 variables and constraints.

GIPALS - Linear Programming Environment it was specially designed to solve , export and import linear programs.

GIPALS can find the solution of any linear program or state that the linear program does not have a solution.

The main features of GIPALS User Interface are:

- The maximum number of variables is 500,000.
- The maximum number of linear constraints is 500,000.
- Direct input LP in sparse (using a grid) and compact form (using special constraint body editor).
- Import LP from files in MPS (Mathematical Programming System) format.
- Export LP to files in MPS format.
- Tracing variable values at each iteration.
- Store LP in XML format.
- Export the solution in CSV (Comma-delimited), Tab-delimited or HTML file formats.
- Flexible debug options.
- Multi-Document Interface (MDI) allows to work with several LP simultaneously.

The main features of GIPALS Linear Solver are:

- Primal-Dual Interior Point Method (Mehrotra Predictor-Corrector).
- Adjustable Preprocessor.
- Scaling of the LP.
- Detection and extracting dense columns.
- Sparse Cholesky factorization.
- Minimal degree ordering, with supernodes.
- Higher order Gondzio correction strategy.
- Iterative refinement (using preconditioned conjugate gradient algorithm).
