A couple problems with timing... 1. In my limited spare time I've just done the switch over from depth based to time based searching. I am now having difficulties coming up with an algorithm to choose the amount of time which should be spent searching for each move. This is a trivial task if the time controls are x moves in y minutes but if the time controls are simply x minutes for the whole game (like on ICS), then what's the most efficient way to use the time? 2. I am developing in C under linux and using the clock() command for all timings. The problem I have is that when it says that it took, for example, 10 seconds to search, it's in actuality more like 25 seconds. At first I thought that I had some kind of problem with casting or arithmetic but I checked all that. I also examined crafty's code and it seems exactly the same as far as usage of clock() is concerned. Then I thought that maybe my clock chip was malfunctioning, but if this were the case then my system would not be keeping accurate time,... but it is. Therefore I have no idea what the problem could be, but it's a pretty significant one as far as I'm concerned. Any ideas? Much thanks, Alex Boby
