Introduction to Simulated Annealing
· Simulated annealing is a stochastic algorithm. Because random variables are used in the algorithm the outcome of different trials may vary even for the exact same choice of cooling schedule. Moreover the convergence to the global optima of simulated annealing is only achieved when algorithm proceeds to infinite number of iterations.

What is Simulated Annealing
· Simulated annealing uses the objective function of an optimization problem instead of the energy of a material. Implementation of SA is surprisingly simple. The algorithm is basically hill-climbing except instead of picking the best move it picks a random move. If the selected move improves the solution then it is always accepted.

· There are a couple of things that I think are wrong in your implementation of the simulated annealing algorithm. At every iteration you should look at some neighbours z of current minimum and update it if f(z) < minimum. If f(z) > minimum you can also accept the new point but with an acceptance probability function.
