### Why is the usual simulated annealing algorithm using a Boltzmann probability?

I've coded a personal version for the simulated annealing problem, and I was wondering why, (other than by analogy to the physics), the probability is $$p = e^{-\dfrac{\Delta \text{length}}{T}}$$ (...

### combinatoric grouping optimization problem based on time interval overlap, weight constraint, and distance minimization

Let each element be an individual. Consider that an individual is defined such that each individual has a time range, weight, and location. The goal is to group together individuals whose time ranges ...

### How to improve convergence to an equilibrium value, & damp oscillation?

I am developing a program which seeks strategies for the players A, B in any of a family of simple 2-player gambling-games. The program iterates, using a genetic algorithm to determine, from the ...

### How to solve the optimization of bin packing using the decision version

Let us say the optimization version of the bin packing problem asks you to give a packing using the fewest bins possible and the decision version asks if it is possible to pack the bins into $k$ bins. ...

### What algorithm should I use for the following problem?

Suppose we have 2 lists: List $G$: the goal, contains goal items each comes with a specific amount, $$G = \{i_1 \times Item_1, i_2 \times Item_2,\dots, i_n \times Item_n\}$$ List $I$: a list that ...
