I'm trying to solve the TSP with Branch and bound algorithm.
I must build a matrix with costs but I have this problem: I have city with coordinates x and y.
The cost of traveling is ceil(ceil(sqrt((x1-x2)^2+(y1-y2)^2))/v)
+ days spent in the city. V is speed.
Days spent in the city depends from day when w comes to the city. For example if we arrived on Monday(t1) to city 1, we stay for 9 days but if we arrived on Tuesday, then we stay in the city for 4 days.
x y t1 . t7 city 1. 79 -36 9 4 8 5 5 7 8 city 2. 8 67 6 9 2 1 9 9 1 city 3. 29 57 7 5 10 8 10 9 4
How can I solve this problem using branch and bound algorithm?
