Hello Henk,

I notice Skipper makes reasonable increases in Elo each maybe 50 Elo points. Why do you think other programs like Andscacs are starting at 2600 Elo and a few years later they are at 3200 Elo?

thank you

Sean

[hgm]

I wouldn't say Skipper makes reasonable Elo increase, for the Elo range it is in. After many years it still around the level of Fairy-Max. As an exercise I once wrote a completely new engine from scratch, (KingSlayer), and after one week it was already 150 Elo better than Fairy-Max. That amounts to 300 Elo per day.

So another four days work and we have a new world champion.

I'm not a serious average developer so Skipper is an exception. I don't like serious testing and I copy too less. I am already glad if I have no bugs in move generator after each 'improvement'.

Fifty elo per year is a long term average over twenty years.

I already knew I was doing fine. Thank you. But no need to repeat that all the time. All these compliments make me shy.
