Inconsistent APS with LiteRumble

Here is a Python script that calculates APS correctly. Use this script when you want to align with LiteRumble.

import os
import gzip
import xml.etree.ElementTree as ET

from statistics import mean


roborunner_dir = os.path.expanduser('~/roborunner')  # replace with your roborunner directory


def get_aps_dict(bot):
  scores = ET.parse(gzip.open(f'{roborunner_dir}/data/{bot}.xml.gz', 'r')).getroot()

  from collections import defaultdict
  aps_raw = defaultdict(list)

  for bot_list in scores:
    for battle in bot_list:
      battle_scores = {}
      total_score = 0

      for robot_score in battle.findall('robot_score'):
        name = robot_score.find('name').text
        score = int(robot_score.find('score').text)
        battle_scores[name] = score
        total_score += score

      aps = 100 * battle_scores[bot] / total_score

      for name, _ in battle_scores.items():
        if name != bot:
          aps_raw[name].append(aps)

  return dict((name, mean(aps)) for name, aps in aps_raw.items())
