The mathematician in me is fascinated by the various roles that constraints play in optimization problems: sometimes they make them much harder to solve; other times, much easier. And the artist in me is fascinated by the roles that constraints play in art. All artists deal with constraints, and many choose to impose constraints upon themselves. The benefit of this was well expressed by Joseph Heller (paraphrasing T.S.~Eliot): "If one is forced to write within a certain framework, the imagination is taxed to its utmost and will produce its richest ideas."
A triptych of Hamiltonian-cycle portraits of William Rowan Hamilton, Lin-Manuel Miranda, and Linda Hamilton. Each has 4096 vertices. Each is a Hamiltonian cycle of the same graph, KiKn64x64. The vertex set is the squares of a 64x64 chessboard. The edge set are the moves that can be taken by a chess king or knight. Each Hamiltonian cycle was obtained by integer-programming-based local search, using Gurobi to solve the integer programs.
A triptych of Hamiltonian-cycle portraits of William Rowan Hamilton, Lin-Manuel Miranda, and Linda Hamilton. Each has 4096 vertices. Each was produced by solving a 4096-city TSP. The optimal tours were found using the Concorde TSP Solver.
