A gravity-aware 3D spatial packing system that places multiple cuboid items inside a fixed container using deterministic heuristics. It sorts items, checks collisions, enforces support under gravity, computes valid (x,y,z) positions, validates constraints, and visualizes final stacking for correctness in a clear, stepwise pipeline.

A high-performance C++20 engine for exhaustive arithmetic search space mapping and expression synthesis. Deterministically explores AST configurations to resolve target-value problems.
