#1836 accepted feature request
Add reheating to simulated annealing

Description
Reheating allows simulated annealing to diversify the search. A general strategy should be identified and added to the current algorithm that does not require an extensive amount of parameters, but which is able to achieve better solutions on e.g. TSP and QAP instances.

comment:9 Changed 8 years ago by jschiess
[14452] First version of new reheating:
Includes reheater by abeham, that reheats continuously based on an acceptance threshold, and a reheater that reheats the temperature by a fixed amount everytime N consecutive soultions are rejected.

r15295: SA reheating strategies: Refactoring (jschiess)
r15299: reverted trunk changes
We perform trunk merges after the code has been reviewed by one of the more experienced developers. I reverted the changes in the trunk. If you feel that the development is finished and the code is tested and stable, please put the milestone 3.3.16 and give me the ticket for review.

I only accidently commited it to trunk. Thank you for reverting and commiting it here. I still have to test everything.
