Re: Efficient time checking using the interval timer

A word of caution on signals: A signal handler can potentially be called at any time, during any operation. Inside of a signal handler, a lot of functionality is not available as one is only supposed to call async-signal-safe functions. Calling an unsafe function can yield to very subtle, hard to fi...

Re: Just say NO

The actual problem with linked lists is its inherent cache-unfriendlyness. In the worst case, traversing a linked list with N elements will result in N different cachelines are being loaded from main memory, even if all N elements would fit into a single cacheline. Consider using a deque instead.

Re: REAL Elo Machine playing humans

There's another reason that makes comparisons even more difficult, namely the hardware the engine runs on. I suppose most engine-engine matches are played with both engines on the same computer. If engine A is 100 elo stronger than engine B on a very slow computer, it would likely be the same on a c...
