Maybe you used a time control where your engine is less performing, or that limited field of opponents is particularly bad for Caffeinated. My testings are based on a sort of Swiss system, and the resulting ratings look quite accurate (if you ask me, of course
).
of course
The bad thing is 22% of crashes. Have you ever had any?
Yes but not that much.
I'll look into it.
It has been quite a while since I wrote a java program so I have to figure out first how to let it produce a coredump or so to aid debugging.
Thanks for your work.

Ok at least one type of crash (if not all) came from out-of-time handling.

It now tries to do something sensible if it had not enough time to even do the first iteration.
Also a tiny pondering improvement.

Good news: crashes have disappeared!

The performance of this version is slightly worse, but consider the error bars.

Hopper Engine v1.1
Thanks to author jonathanmcdermid
https://github.com/jonathanmcdermid/Hop ... ngine-v1.0
Stable Version
Largest changes since v1.0 are functioning pawn hash tables and a more sophisticated evaluation function. The engine should be stronger than it currently is with the features that are already implemented, so future versions will likely contain less new features and more refined versions of current ones.
Current Features:
negamax algorithm
forsyth–edwards notation
material evaluation
mobility evaluation
alpha-beta pruning
iterative deepening
principle variations
transposition tables
pawn hash table
zobrist keys
null moves
zugswang detection
quiescent search
dynamic aspiration windows
pinned piece detection
double check detection
threatened squares
killer moves
perft
principal variation search
static exchange evaluation

I can't see any on his repository. Anyway you can ask him there, or can write it by yourself.
