No. That's the point. It is a simulation of a complex system. The interactions between the mice are everything.

It is not simultaneous. I use the Gillespie technique for stochastic simulation. I select a mouse at random to change boxes, depending on its transition rate compared to the transition rate of the system as a whole.

Exactly.

There are four types of meeting: mouse 1 entered -> mouse 2 entered -> mouse 2 left -> mouse 1 left; mouse 1 entered -> mouse 2 entered -> mouse 1 left -> mouse 2 left; mouse 2 entered -> mouse 1 entered -> mouse 1 left -> mouse 2 left; mouse 2 entered -> mouse 1 entered -> mouse 2 left -> mouse 1 left.

Then the meeting record contains the times the two were together and the duration of this.

The dumb approach is very slow. Would it be a good idea to read all stay results in Scala (or whatever) and try to do the searching in memory, completely eliminating th db? But then the comparisons would be more expensive...

Thank you! But I am thinking, could I be able to obtain easily the duration of each meeting using this setup? This is what I would ultimately need (to construct the empirical cdf, social network, etc.)

i would be curious to learn more about you, Pavel. what do you study? are you from Bulgaria?
