WebbSimulated Annealing Step 1: Initialize – Start with a random initial placement. Initialize a very high “temperature”. Step 2: Move – Perturb the placement through a defined move. Step 3: Calculate score – calculate the change in the score due to the move made. Step 4: Choose – Depending on the change in score, accept or reject the move. WebbA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
