Hey guys,
it's been a while. I used to be quite active on CCC a long time ago. Back then I was developing a simple engine called Alice. It's amusing that early versions of that program still appear in some engine competitions, mostly losing on time and behaving badly in general
Anyway, I've embarked on a rewrite, hoping I've learned a few things in my previous attempt. In particular I'll be focusing on search efficiency, something I have neglected so far. I'll be using g++ and 64-bit Linux. If there's interest I'll post updates and results.
Cheers,
Sven.

Re: Alice: A reintroduction
Welcome back, Svein!
I remember my engine Prédateur found its first deep mate against Alice, in this position that I now use to check that nothing is broken (it now needs less than 4k nodes to solve it) :
[d]rnbqkbnr/pppp1Np1/4ppB1/4P2p/1P6/2N2Q2/PBPP1PPP/R4RK1 w - - 4 14

Re: Alice: A reintroduction
Hi Sven
As a linux user I'm interested in (almost) any engine that can run in this platform.
Can you provide a link to your project? (I've made a search on the web but I haven't been able to find anything useful).
Anyway, I'd be interested in the develop of this project

The old Alice is still playing here (see my H group that will start in September). If you have something ready by then, be sure to send it to me

Re: Alice: A reintroduction
It's always cool to see a new version of a golden oldie like Alice. Really neat to see the new UCI version of Ziggurat too, played a lot of games with that program back in the Windows 3.1 days.
