v1.0

• Fix a bug in multipv output.

See mea.exe in mea.zip.

v0.7.0

If movetime is 0 and depth is specified, send command,
go depth x

This is for engines that do not report search info properly when set to
search at depth 1 and with presence of movetime.

Example to force some engines to report its search info at depth 1, do the following:
mea.exe --movetime 0 --eoption "depth=1" ... other option and flags

mea.exe is in mea.zip file.

v0.6.5

A. Changes

• Synchronize timestamps from log and movetime elapsed calculation.

• Add --runenginefromcwd for Rybka engine.
  Usage:
  mea.exe --epd test.epd --engine rybka.exe --eoption "Max CPUs=1" --hash 64 --movetime 100 --log --runenginefromcwd

• Help

usage: mea.exe [-h] -i EPD [-o OUTPUT] -e ENGINE [--eoption EOPTION] -n NAME

               [--log] [--runenginefromcwd]

Analyzes epd file having multiple solution moves with points

optional arguments:

                        for xboard engine, set this to 1 if it will send a
                        move in san format, default=0
  --stmode {0,1}        for xboard engines, set this to 0 if it does not
                        support st command, default=1
  --protover {1,2}      for xboard engines, this is protocol version number,

  --runenginefromcwd    Run engine from mea folder

MEA v0.6.5

B. File

• mea.zip
  It contains mea.exe.

v0.6.3

Major change

• Allow illegal uci move format for promotion moves. a2a1Q or similar from engine is now converted to a2a1q.

Files

• mea.exe can be found in mea.zip

v0.6.0

Major changes

• Always send isready before sending position command. This would guarantee that engine is in sync with mea.
• Remove monitoring of actual Lc0 memory usage for now to minimize test delays. Will be added later after optimization test is completed.
• Add infinite option, useful for uci engines that does not run properly on movetime or depth commands.
• Reduce stop time margin.
• Reduce time margin per pos.
• Run engine at the folder of the engine. This would prevent log files etc cluttering at the folder of mea. This would also allow the engine running on adapter to run, even if mea is not in the same folder with the engine and adapter.
• Fix go command for cecp engines.
• Save epd and bm for cecp engines, useful for simex.
• Modify file naming of epd output for simex.

v0.3.10

A. Feature

Analyze epd with move points and generate results in html, csv and text formats. It will output log and epd with engine evaluation and depth.

Sample html output
