Do you spend hours solving algebraic matrices by hand, only to have a single sign error ruin your entire Linear Optimization exercise? Understanding the Simplex Algorithm in Operations Research can be frustrating. Current tools are clunky, confusing, and seem like they're from the 90s. DISCOVER SIMPLEX EDUCATIONAL The high-fidelity academic tool designed exclusively for iOS and iPadOS that transforms complex matrices into a fluid, readable, and intuitive visual experience. Perfect for students of Industrial Engineering, Economics, Business Administration, and optimization professionals. WHAT YOU CAN DO: โ€ข Dynamic Model Builder: Switch between Maximization (Max Z) and Minimization (Min Z). Enter constraints with operators (โ‰ค, โ‰ฅ, =). โ€ข Intelligent Engine: Automatic conversion to Standard Form (injecting slack, surplus, and artificial variables). โ€ข Special Case Detection: Identifies unique, multiple (infinite), unbounded, or infeasible solutions without infinite loops. โ€ข Local History with SwiftData: Audit your past problems instantly, without re-entering large matrices. CHOOSE HOW TO LEARN: 1. FINAL RESULT MODE (Free): Your executive success card. Visualize the optimal vertex with specific color codes (Green for unique solution, Purple for multiple). 2. STEP-BY-STEP MODE: An interactive learning log that details each iteration and pivot in ultra-readable, single-spaced tables. Access it for free through rewarded ads or unlock it forever. PRO PASS (One-Time Payment - No Subscriptions): Completely remove ads, unlock unlimited offline Step-by-Step Guides, and export your completed exercises as LaTeX code or professional PDFs. Designed following Apple's guidelines to offer you a clean, dark, and fast interface. Pass your course without frustration!

Linprog solves linear programming and optimization problems step by step โ€” and shows the complete worked solution, not just the final answer. From a classic simplex tableau to the travelling salesman problem, it covers the operations research methods you actually study, and works fully offline. Whether you're a student checking coursework or solving a problem set, Linprog walks through each method in full, saves your work so you can revisit it, and presents results as exact fractions or decimals. OPERATIONS - Simplex method calculator - Dual simplex method calculator - Transportation problem โ€” potential method calculator - Assignment problem โ€” Hungarian method calculator - Travelling salesman problem calculator (TSP) - Game theory calculator - Dynamic programming calculator LINEAR PROGRAMMING Maximize or minimize a linear objective function under linear constraints. Linprog handles the full setup โ€” objective, constraints, and bounds โ€” and shows every pivot of the simplex (and dual simplex) algorithm so you can follow exactly how the optimum is reached. FEATURES - Full step-by-step solutions for every method - Custom keyboard for fast, convenient data entry - Save and edit your solutions - Works without an internet connection - Results as ordinary or decimal fractions Web version: https://linprog.com
