UCI_Elo and UCI_Limit meaning #24

i'm enthousiastic about the new version v3.0 ! Your README gives remarkable details.

there's a small bug in your settings : the UCI_Elo and UCI_Limit options are not shown in the CuteChess GUI option pane .. that's because they're not defined properly :

option name UCI_Elo type spin default 3300 min 1100 max 3200
option name UCI_Limit type spin default 3300 min 1100 max 3200

the default values are higher then the max .. i'm sure this is easy to correct.

can you elaborate on these options ? they seem an interesting setting for practical play, but confusing to me : what's their difference ? How to them (both) ? Patricia does not have MultiPV, but does e.g. UCI_Elo = 2300 mean Patricia will play let's say the fifth best move ?

That bug was fixed almost immediately after release. The 3.0 release has updated exes and a note saying when the update happened and why it did.

There is no difference between the two; I had UCI_Elo support before, then added UCI_Limit because someone wanted to port Patricia into a game using UCI_Limit to weaken the engine.

UCI_Elo = 2300 means Patricia will play at a 2300 CCRL level (approximately, based on testing). The levels/elos are just the Elo strength that you're weakening her down to. (Be warned, everything over 3000 is full strength Patricia.)
