Ranking teams equal on points in a pool based on who won the game they played

Question

I\'m writing an application that calculates the ranking of teams in the pool stages of a rugby competition (Rugby World Cup 2015, but it could apply to many other pool-based

Answer 1

I want to add some other suggestion. Because your current problem have some contradictions and may not have a proper answer with current rules.

• First picture 4 team tie in same rank. If you use the information of the first 4 rows. You get a positions D, A, B, C but then last two can't be enforce.
  • In NFL they have some tie break called inside conference win. So you could count how many win each team have inside this group as a way of order.
  • So now all condition are pair comparasion.
  • In this case A and D have more wins and D beat A.
  • Now C beat B and A beat C. And you have a real order.
• But as show in picture 2 you can have everyone tie with 2 win.

My guess is you should analyze the restrictions. Maybe the order of rules is different and you can reduce THIS problem to one where only two team are tie.
