sim - Simulate Interactive Maths

Role

cp4.vn/sim is for interactive geometry-based visualization of math and algorithms.

It exists when reading code or static diagrams is not enough and learners need to replay states, inspect transitions, and see why each step changes the result.

Graph visualized using ImGui

Data extracted from graphs

Purpose

• Visualize graphs, geometry, states, transitions, tables, and algorithm flows.
• Make abstract ideas easier to inspect, simulate, teach, debug, and present.
• Support educational demos, competitive-programming explanations, and math experiments.

Learning Style

Simulation-based learning: students learn by replaying processes, checking outcomes, and seeing why each action changes the result.

CP4CPP Rules

• Simulations should expose state, transition, input, and output clearly.
• Interactive pages should have a static explanation fallback.
• Simulations should link to their theory page in doc and their learning path in edu when those pages exist.
