Simplex Calculator

Simplex Calculator solves linear programming problems step by step and explains every step. It is made for secondary school, university and management courses. SIMPLEX, TABLEAU BY TABLEAU • Standard form and every tableau, one at a time • Why each variable enters and leaves the basis, with the pivot highlighted • Big M method for ≥ and = constraints • Special cases explained: infeasible, unbounded, multiple optimal solutions and degenerate • Practice mode: you pick the entering and the leaving variable before you see the answer GRAPHICAL METHOD (2 VARIABLES) • Feasible region and exact vertices • Drag the objective line across the region • Zoom, pan and tap a vertex ALGEBRAIC METHOD • All basic solutions, each with its system of equations • Which ones are feasible and which one is optimal SENSITIVITY ANALYSIS AND DUAL • Shadow prices and reduced costs • Ranges for the right-hand sides and for the objective coefficients • A plain reading of the results for business decisions • The dual problem and its solution EXACT RESULTS • Exact fractions, with no rounding errors; decimals if you prefer • Up to 10 variables and 10 constraints • Maximise or minimise, with ≤, ≥ and = constraints EASY TO USE • Enter the problem in a grid or as text (max z = 3x1 + 2x2) • 13 ready-made examples by level: secondary, university, management and special cases • History of your last 30 problems • Share a problem with a link, print the full report or save it as PDF • Light and dark theme, adjustable text size • English and Portuguese • Phones, tablets and computers PRIVATE AND FREE • Free, with no ads and no purchases • No account and no data collection: your problems stay on your device • Works offline after the first launch Made in Portugal by Bica Games.
