v1.2.6

Changes

• improve speed and output with -i switch is used.

v1.2.4

Changes from v1.2

• Optimize group processing (adopted from ordoprep).
• Optimize calculation post-convergence (diversity, etc.)
• Switch --timelog added. It outputs time stamps at each step of the calculation
• This version fixes bugs from v1.2.2 (release deleted)

1.2

Changes

• Long option switches implemented
• When a name from exclude/include file do not match the names from the input PGN file/s, issue a warning and continue
• --no-warnings was implemented to silence the above mentioned warnings.

1.1.8

Changes from 1.1.6

• switch -N includes two parameters. For instance, -N 2 will output ratings with two decimals. If an extra parameter is provided separated by comma, it will control the number of decimals for the score percentage. For example, the default is actually -N 0,1 or -N "0,1". If a second parameter is not provided, the default is used.

1.1.6

Changes

Column width is adjusted automatically if the user provides a low number. This is based on the widest item in the column

1.1.2

Changes from 1.1.0

A switch was added to simplify multiple input files control column format in the output

• -P <file> text file containing a list of PGN file names (multiple input)

The number of input files is now limited by the system memory.

1.1.0

Changes from 1.0.9.8

A switch was added to control column format in the output

• -b <file> format column output, each line being <column>,<width>,"Header"

This switch controls the width of each column in the output and the header of each column.
This <file> consists of a text in which each line has <column>,<width>,"HeaderName".
For instance, if you want to have the item 4 (games total, see manual.pdf), to be 5 characters wide and be named "Points", you will have to include a line like this:

4,8,"Points"

1.0.9.8

Changes from 1.0.9.5

Two switches added to select games from the input file/s

• -i <file> include only games of participants present in <file>
• -x <file> names in <file> will not have their games included

In certain situations, the user may want to include/discard in the calculation only a subset of the games present in the input file/s. Switches -i <file> and -x <file> are used for this purpose. Switch -i includes only the games of participants listed in <file>. In this file, each participant name has to be in different lines. Also, each of those names may or may not be surrounded by quotes. Both are accepted. For this reason, if a .csv file is provided as a list of participants, only the first column is read. In addition, -x could be use to exclude games of participants listed in <file>.

• In the output, the column that contains the score (%) was removed of the symbol %.

1.0.9.5

Changes from v1.0.9.2

Added 3 alternatives for the switch -U

• 12 opponent average error
• 13 number of opponents
• 14 diversity (effective number of opponents based on information theory)

Option 14 is will be equal to option 13 if the number of games among opponents is equally distributed.

1.0.9.2

Changes from v1.0.9

• Bug introduced in 1.0.9, which slowed down simulations, fixed
