Largest Inscribed Rectangles in Geometric Convex Sets

This paper considers the problem of finding maximum volume (axis-aligned) inscribed parallelotopes and boxes in a compact convex set, defined by a finite number of convex inequalities, and presents an optimization approach for solving them. Several optimization models are developed that can be easily generalized to find other inscribed geometric shapes such as triangles, rhombi, and tetrahedrons. To find the largest axis-aligned inscribed rectangles in the higher dimensions, an interior-point method algorithm is presented and analyzed. Finally, a parametrized optimization approach is developed to find the largest (axis-aligned) inscribed rectangles in two-dimensional space.
