PR1195: Time management update

This page contains summary of changes in PR 1195.

It’s basically the same idea as before, just (hopefully) more carefully done.

Idea

The basic idea is that:

By the end of the game, all time should be used.
At the moment of making every move of a game, a search tree should have the same total number of nodes (including reused nodes).

Note: that may be not the best way though, maybe trying to make bestmove to have the same number of visits (rather than tree total) would be actually better.
