"WebbSimulated Annealing, Corana’s version with adaptive neighbourhood. This version of the simulated annealing algorithm is, essentially, an iterative random search procedure with adaptive moves along the coordinate directions. It permits uphill moves under the control of metropolis criterion, in the hope to avoid the first local minima encountered. " - Simulated annealing c++ code
