Master the mechanics of Linear Programming with an industrial-grade, visual Simplex solver. Whether you are an undergraduate student tackling Operations Research homework or an engineer optimizing complex systems, this app provides a high-performance, native environment to solve and visualize linear models. Built with Apple’s Accelerate Framework (vDSP), the engine performs hardware-accelerated matrix operations for desktop-class speed on your mobile device. Why this is the ultimate optimization tool: Visualize the Feasible Region: See your constraints come to life on an interactive Canvas. Plot the quadrant, identify intersection points, and explore the feasible region with intuitive gestures. The Simplex Journey: Watch the algorithm navigate from the origin to the optimal solution. Our "Visual Walker" tracks every iteration, highlighting each vertex transition with a clear, orange path. Professional Grade Logic: Full support for Big-M and Two-Phase methods. Easily handle ≤, ≥, and = constraints without needing to manually convert your model. Precision Entry: Clean, monospaced interface featuring color-coded inputs for coefficients, objective goals, and variable signs. Education-First Design: Perfect for learning the geometry behind the algebra. Follow the path, analyze the coordinate labels, and see exactly where the "Optimal" solution sits in the coordinate plane. Purely Native: No web wrappers or lag. Experience a fluid SwiftUI interface designed for "Engineering Soul"—performance, clarity, and reliability. Student & Professional Value Proposition For Students: Use it as a powerful "Check Your Work" tool. Compare your manual pivot steps against the visual path and verify your feasible region boundaries. For Professionals: Quickly prototype constraints and objectives on the go with a solver that respects hardware limitations and mathematical rigor.

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: • Dynamic Model Builder: Switch between Maximization (Max Z) and Minimization (Min Z). Enter constraints with operators (≤, ≥, =). • Intelligent Engine: Automatic conversion to Standard Form (injecting slack, surplus, and artificial variables). • Special Case Detection: Identifies unique, multiple (infinite), unbounded, or infeasible solutions without infinite loops. • 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!
