Optimization by thermal cycling [PDF]

Physical Review Letters, 2005
Thermal cycling is an heuristic optimization algorithm which consists of cyclically heating and quenching by Metropolis and local search procedures, respectively, where the amplitude slowly decreases.

Two optimization problems in thermal insulation [PDF]

Notices of the American Mathematical Society, 2017
We consider two optimization problems in thermal insulation: in both cases the goal is to find a thin layer around the boundary of the thermal body which gives the best insulation. The total mass of the insulating material is prescribed..
