Editing Simulated annealing (section)

===The basic iteration===
At each step, the simulated annealing heuristic considers some neighboring state ''s*'' of the current state ''s'', and [[probabilistic]]ally decides between moving the system to state ''s*'' or staying in state ''s''.  These probabilities ultimately lead the system to move to states of lower energy.  Typically this step is repeated until the system reaches a state that is good enough for the application, or until a given computation budget has been exhausted.
