WARNING: this is a fairly complex problem, in a king-of-the-hill combat style, with an added randomness to it, the best code may not always win. Please read all rules in full, as it is quite complex!

FLAVOR TEXT

Bill and Steve decided to have a "friendly" duel, however being so rich and smart, decided to let their best programmers try their hand at coming up with the code to beat each other. You are said programmer.

OBJECTIVE

In fencing, your goal is to score the most hits on your opponent, while getting hit the least yourself

MOVES

Your code will have the following choices of "moves"

Attack
Parry
Block
Lunge
AND
Head
Chest
Feet

SCORING POINTS

Attacking beats Parrying, for 1 point
Lunging beats Blocking, for 1 point
Parrying Beats Lunging, for 1 point
Blocking beats Attacking, for 1 point
Lunging ties Attacking, with the lunging player unable to block or parry the next round, and the attacking player unable to attack or lunge the next round
Blocking ties Parrying, with the parrying player unable to block or parry the next round, and the blocking player unable to attack or lunge the next round

HEIGHT OF ACTION

you will also choose a "height" for your action, whereupon the outcomes above only take place if the heights of both players match the attack height. if the heights do not match, both players may no longer select the same action (height is not restricted) as the previous tying rounds, until a point is scored, or all 4 actions have been filled (once a tie is broken, all actions are available again)

CODE REQUIREMENTS

for each round, it should prompt the move of the opponent the previous round (barring round 1), compare it with its own, determine the outcome of the previous round, then output the next round number, the score, and its choice / position for that round

ex:
INPUT: LC (lunge chest)
OUTPUT: previous round: PM vs LC - PM scores! score is now 2-1, action for next round is AH (attack head)

WINNER

the game ends after 50 rounds, or after 3 points have been scored

AGAINST OTHER PLAYERS

the first answer will be given an instant guaranteed win, as long as it functions to actually work/play. Each answer will be evaluated, in order of posting, against the previous winner, and if winning, will be declared the new winner. I ask that while winning, or waiting to compete, that you do NOT change your code. Once being defeated, you may no longer compete for championship status with that same language, you may however submit a different language answer (must be significantly different, no using variations of the same base stuff).

I will attempt to run each challenge and will post the results in the comments of the champion and challenger, as well as declare a new winner - as I may not be able to run every language, especially some of the more obscure ones, I ask any possible help you can give to make sure your answer gets run be taken into consideration. Thank you!

    \$\begingroup\$ note: targetting the current winners algorithm to counter that player is in the nature of fencing, and this is king-of-the-hill, so such action is not only allowed, but also ENCOURAGED! - try to come up with some method of generating results, obfuscating your code, or some other way to "guard" yourself, and figure the best way to "attack" the other player's code! -- PLEASE KEEP ALL DISCUSSION CIVIL -- \$\endgroup\$ – NRGdallas Sep 7 '12 at 21:59
  • \$\begingroup\$ once defeated, if you want to offer insight into how you did things, why you did things a certain way, etc, in comments or by modifying your answer, feel free to. While your code is in line, however, please refrain from editing :) \$\endgroup\$ – NRGdallas Sep 7 '12 at 22:00
  • \$\begingroup\$ Is your example correct? It seems to mangle an input of LC into an action of LM. \$\endgroup\$ – Peter Taylor Sep 8 '12 at 8:33
  • \$\begingroup\$ What about randomness in the solution? Must the match be deterministic? If not, how will the judge select the seed, and how many games will be played between two programs, just one? The robocode competitions usually have 10, to limit the effects of blind chance. \$\endgroup\$ – vsz Sep 8 '12 at 9:03

    \$\begingroup\$ I don't really like how this is designed. I think you should come up with the code to run the match by running 2 submitted programs, relaying the moves and calculating the scores. The fencing programs should just print their moves to stdout and read the opponent's moves form stdin. \$\endgroup\$ – aditsu Mar 5 '13 at 17:42

En garde!

My warrior combines unpredictability with a keen eye for weakness in his opponent's stance. He's pretty confident he'll be able to dispose of aggressive foes but his trainer (me) may have failed to anticipate certain scenarios or, perhaps more worrying, may have misinterpreted the rules (bugs!!).

Anyway I'm new so hopefully this is an ok format for the code:

I claim the hill!

This includes a framework which takes care of the match, input and output. All you have to do is define your own versions of two functions in the "A.I.h" header which define the first move and every other move.

This compiles in VS2012 (free version). To the best of my knowledge it will compile in any standards-compliant compiler.

I call this A.I. "Unsophisticated Barbarian." I'm sure it won't take long for someone to beat it.

    \$\begingroup\$ just noticing a potential code flaw - when you code for a block, it still returns the move of a lunge! -- remember, per the rules, no editing is allowed until you are defeated \$\endgroup\$ – NRGdallas Mar 7 '13 at 14:40

    \$\begingroup\$ Good point. That may mean the AI attempts illegal moves. What happens in that situation? \$\endgroup\$ – Arkady Mar 7 '13 at 15:21
  • \$\begingroup\$ I'd also like to add that I consider the framework public and all who wish to borrow it and just rewrite the two AI functions are free to do so. \$\endgroup\$ – Arkady Mar 7 '13 at 15:24
  • \$\begingroup\$ any illegal move is an instant round loss. \$\endgroup\$ – NRGdallas Mar 8 '13 at 21:59
