Traveling Salesman Problem (TSP) using Simulated Annealing

A GUI for sovling TSP's using Simulated Annealing

Description

simulatedannealing() is an optimization routine for traveling salesman problem. Any dataset from the TSPLIB can be suitably modified and can be used with this routine. A detailed description about the function is included in "Simulated_Annealing_Support_Document.pdf."

A GUI is used with the core function to visualize and to vary annealing parameters.

Four sample data set from TSPLIB is provided. You can create your own data set by following a simple procedure given in the supporting document.

You can access the TSPLIB by following this link
http://www.iwr.uni-heidelberg.de/groups/comopt/software/TSPLIB95/

Feel free to drop in your comments, suggestions, bugs and mistakes in the algorithm.

Note: Simulated Annealing is a memory intensive and processor intensive algorithm. A big data set may take hours depending on your computer configuration.

• MATLAB release: MATLAB 7.1.0 (R14SP3)
• Other requirements: Requires a lot of memory. Minimum recommended 256 MB RAM

Good.....
Try to dynamic anealing to improve the search...

Would you like to give the file 0f 101 cities to try my algorithm.

[alireza kashanipour]

Very good dear,
but i think we must replace 10 by 1 in line 55 simulatedannealing.m
  if complete_temperature_iterations >= 1
it's excellent as a tutorial,and tanx alot

Please help me in GUI programming in MATLAB.
And i don't know why there are some errors in running GUI in this program.
I'm using MATLAB7. When I run stsp.fig, there are some errors. I don'n have any document that guides me in GUI in Matlab, please help me.

[Long Phan Hai]

I wonder in function simulatedannealing, why there is only one loop?? According the algorithm, there are 2 loops.

[Richard L. Lachance]

In swapcities, the correct way to select a random city is:

city_1=floor(length(inputcities)*rand(1))+1;

and the same applies for city_2, and
numberofcitiestoswap in simulatedannealing.m

Otherwise the distribution is not uniform.
This helps the algo to give correct answers.
