BASIC Programming Compiler vs Simplex Linear Programming

Write BASIC code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets! BASIC (Beginner's All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use. This app uses the free/open source (GPL) FreeBASIC compiler (https://www.freebasic.net) as backend. FreeBASIC is a high-level programming language supporting procedural, object-orientated and meta-programming paradigms, with a syntax compatible to Microsoft QuickBASIC. Features: - Compile and run your program - View program output or detailed error - Select and run chunk of codes - Custom keyboard for easy input of frequently used characters - Optimized for connecting with external physical/bluetooth keyboard - Advanced source code editor with syntax highlighting and line numbers - Open, save, import and share bas files. - Language reference - Install packages Limitations: - Internet connection is required for compilation - Maximum program running time is 20s - Some file system, network and graphics functions may be limited - Only 1 file can be run at a time - This is a batch compiler; interactive programs are not supported. If your program provides an input prompt, enter the input in the Input tab prior to compilation. See the Reference tab in the app for code examples

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.
