This version introduces several improvements to the AI and a new help mode.

Changes:

• Improved offensive AI
  • Makes more efficient discards with exact shanten calculation.
  • Makes better decisions with expected score calculation (push/fold judgement, efficiency vs. value).
  • Does not make calls with cheap and slow hands anymore and takes a few more factors into account when considering calls.
• Improved defensive AI
  • Calculates the expected score for the opponents and tries to avoid dealing into expensive hands.
  • More accurately predicts the opponents chance to be tenpai and chance to deal into them with a tile.
  • Considers more factors for defense, like tiles near dora and near the discard on the opponent's riichi turn which are considered more dangerous.
  • Predicts some yaku for open hands and tries not to deal into them.
  • Added Sakigiri (discarding dangerous tiles earlier). The weight can be controlled with the SAKIGIRI parameter (the default 1.0 setting is quite low).
  • Added an option to force the bot to keep a safetile (until 1 shanten). This behavior is disabled by default and can be turned on by setting KEEP_SAFETILE to true.
• New parameter PERFORMANCE_MODE
  • Can be set from 0 (fastest calculation, but worse decisions) up to 4 (highest calculation time, best decisions). Default is 3, which is nearly as smart as 4, but reasonably faster.
  • When the bot takes more than the allowed 5 seconds per turn it will lower the performance mode automatically after a while.
• Improved the room selection in the GUI. Room names are now translated based on the game language and only available rooms for the rank are displayed.
• Added help mode: When turned on in the GUI the bot will not discard tiles automatically anymore, but instead display a hint in the textbox.
  • Emojis instead of tile names can be turned on or off with the USE_EMOJI parameter.
