I am currently working on a project (TSP) and am attempting to convert some simulated annealing pseudocode into Java. I have been successful in the past at converting pseudocode into Java code, however, I am unable to convert this successfully.

The pseudocode is:

T0(T and a lowercase 0)

Starting temperature Iter Number of iterations

λ The cooling rate

1. Set T = T0 (T and a lowercase 0)

2. Let x = a random solution

3. For i = 0 to Iter-1

4. Let f = fitness of x

5. Make a small change to x to make x’

6. Let f’ = fitness of new point

7. If f’ is worse than f then

8. Let p = PR(f’, f, Ti (T with a lowercase i))

9. If p > UR(0,1) then

10. Undo change (x and f)

11. Else

12. Let x = x’

13. End if

14. Let Ti(T with a lowercase i) + 1 = λTi(λ and T with a lowercase i)

15. End for Output: The solution x

If somebody could show me a basic mark-up of this in Java I would be extremely grateful - I just can't seem to figure it out!

I am working across multiple classes using a number of functions (which I will not list as it is irrelevant for what I am asking). I already have a smallChange() method and a fitness function - could there be a chance that I would need to create a number of different versions of said methods? For example, I have something like:

public static ArrayList<Integer> smallChange(ArrayList<Integer> solution){ //Code is here. }

Could I possibly need another version of this method that accepts different parameters? Something along the lines of:

public static double smallChange(double d){ //Code is here. }

All I require is a basic idea of how this would look when written in Java - I will be able to adapt it to my code once I know what it should look like in the correct syntax, but I cannot seem to get past this particular hurdle.

Thank you.
