Everyone starts with 100 hp. Each round, 2 players are chosen at random from the pool of contestants who have not yet competed in that round. Both players pick a number between 0 and their current hp, and reveal those numbers at the same time. The player who chose the lower number immediately dies. The other player subtracts their chosen number from their remaining hp and goes on to the next round.



The tournament works like this:



From the bracket of contestants, 2 are chosen at random. They face off, and one or both of them dies. A player dies if:



  1. They choose a number smaller than that of their opponent

  2. Their hp drops to or below zero

  3. They tie three times in a row with their opponent

In the case of ties, both players simply generate new numbers, up to 3 times. After the faceoff, the survivor (if any) is moved to the pool for the next round, and the process repeats until we have exhausted the current round pool. If there is an odd number in the pool, then the odd one out moves on to the next round for free.



Your task is to write a function in python2.7 which takes as inputs your current hp, a list of your opponent's guess history, and an integer ties which tells you how many times you have already tied with your current opponent, and an integer which tells you how many bots are still alive (including you). Note that the history does not include ties. The function must return an integer between 0 and your current total hp. A few simple examples, which ignore ties, are shown below:



def last(hp, history, ties, alive):
 ''' Bet a third of your hp at first, then bet your opponent's last guess, if possible '''
 if history:
 return np.minimum(hp-1, history[-1])
 else:
 return hp/3

def average(hp, history, ties, alive):
 ''' Bet the average opponent's guess so far, on the assumption that guesses will tend downward '''
 if history:
 num = np.minimum(hp-1, int(np.average(history))+1)
 else:
 num = hp/2
 return num

def random(hp, history, ties, alive):
 ''' DO YOU WANT TO LIVE FOREVER?! '''
 return 1 + np.random.randint(0, hp)


If your function returns a number larger than your hp, it will be reset to 0. Yes, it is possible to kill yourself. Under these rules it is possible that there is no winner, and the last two contestants kill each other. In that case both finalists get half a point each.



Once I get a pool of candidates I will run a few thousand tournaments to get some statistics. The goal of this is to find interesting ways to predict opponents' bets, so I am open to providing more input information for your function if it would make it more interesting to do so. I'm not married to the tournament format, so if someone suggests a more interesting or fair format I'll implement both and we can compare.



This will be a very high-variability puzzle, so I will run at least N=100000 tournaments to gather good statistics before declaring a winner.



This is my first programming puzzle attempt, so critiques are welcome!



EDIT: bots have really interesting interactions depending on their history-dependent behavior. The presence or absence of a particular bot type can dramatically impact the average performance of another bot if the betting pattern of one has big effects on the others. This should be pretty neat to analyze.

    Should there also be a parameter for how many opponents are left in the tournament? Having a rough idea of how many rounds the bot has left could be useful information.

    Based on some quick testing, the kamikaze bot deosn't change much - all it does is remove another bot from the round at random, which, over a large enough number of tournaments, simply averages to zero. The One hot is neat, though. Without it, my AverageBot tends to do the best - but if there are a few OneShots in play, is skews the average toward large numbers and tends to make the AverageBots die off quickly. Same for LastBot. You can really mess with the behavior of other robots by skewing your own betting patterns. With OneShot in play, RandomBot wins . Without it, AverageBot wins.

Bot will attempt to bid higher than its opponent can bid. Won't win against a kamikazi, but against future bots, it might work out.

The pathetic attempt at a bot that analyzes the history of its opponent



def pathetic_attempt_at_analytics_bot(hp, history, ties, alive):
 '''Not a good bot'''
 if history:
 opp_hp = 100 - sum(history)
 if alive == 2:
 if hp > opp_hp:
 return hp - 1
 return hp
 if hp > opp_hp + 1:
 if opp_hp <= 15:
 return opp_hp +1
 if ties > 0:
 return hp #Just give up, kamikaze mode
 return opp_hp + 1
 return opp_hp
 else:
 n = 100 // (alive - 1) + 1 #greater than
 if n >= hp:
 n = hp - 1
 return n


If there is previous history of its opponent, then it calculates its opponent's hp. Then, it does one of the following:



  • If its opponent is the last opponent alive, then it will bid one less than its hp.

  • If its opponent is not the last opponent alive but the opponent has less than 16 hp, then it will outbid its opponent's hp.

  • If its opponent is not the last opponent alive and there is a history of ties, then it will bid its hp because it is bored of ties.

  • Otherwise, it will outbid its opponent.
    If there is no history, then it does some fancy calculations that I hacked together and bids that. If the value exceeds 100, then it automatically bids its hp minus 1.

I hacked this code together during work and this is my first submission, so it probably won't win or anything, and it'll lose to the kamikaze.

The One hot is neat, though. Without it, my AverageBot tends to do the best - but if there are a few OneShots in play, is skews the average toward large numbers and tends to make the AverageBots die off quickly. Same for LastBot. You can really mess with the behavior of other robots by skewing your own betting patterns. With OneShot in play, RandomBot wins . Without it, AverageBot wins.

    Based on some quick testing, the kamikaze bot deosn't change much - all it does is remove another bot from the round at random, which, over a large enough number of tournaments, simply averages to zero.

The pathetic attempt at a bot that analyzes the history of its opponent



def pathetic_attempt_at_analytics_bot(hp, history, ties, alive):
 '''Not a good bot'''
 if history:
 opp_hp = 100 - sum(history)
 if alive == 2:
 if hp > opp_hp:
 return hp - 1
 return hp
 if hp > opp_hp + 1:
 if opp_hp <= 15:
 return opp_hp +1
 if ties > 0:
 return hp #Just give up, kamikaze mode
 return opp_hp + 1
 return opp_hp
 else:
 n = 100 // (alive - 1) + 1 #greater than
 if n >= hp:
 n = hp - 1
 return n


If there is previous history of its opponent, then it calculates its opponent's hp. Then, it does one of the following:



  • If its opponent is the last opponent alive, then it will bid one less than its hp.

  • If its opponent is not the last opponent alive but the opponent has less than 16 hp, then it will outbid its opponent's hp.

  • If its opponent is not the last opponent alive and there is a history of ties, then it will bid its hp because it is bored of ties.

  • Otherwise, it will outbid its opponent.
    If there is no history, then it does some fancy calculations that I hacked together and bids that. If the value exceeds 100, then it automatically bids its hp minus 1.

I hacked this code together during work and this is my first submission, so it probably won't win or anything, and it'll lose to the kamikaze.

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
