Features & Capabilities

OR Simplex Step-by-Step is an offline Android solver for Operations Research and linear programming. It supports classical, Two-Phase, and Big-M Simplex methods, Integer Programming with Branch and Bound, 2D graphical analysis, and 3D polytope visualization for three-variable problems.

The app also includes sensitivity and post-optimal analysis, transportation methods, MODI/U-V optimization, the Hungarian Assignment Algorithm, and Johnson’s Job Sequencing algorithms. Students can follow plain-language, step-by-step iterations, use exact fraction arithmetic, save problem history, and work in eight languages without an account, internet connection, or tracking.
