WebMar 6, 2024 · Simulated annealing is an effective and general means of optimization. It is in fact inspired by metallurgy, where the temperature of a material determines its behavior in thermodynamics. Likewise, in simulated annealing, the actions that the algorithm takes depend entirely on the value of a variable which captures the notion of temperature. … WebIn simulated annealing, the equivalent of temperature is a measure of the randomness by which changes are made to the path, seeking to minimise it.
