Hi, so I chose this problem as my first foray into core.logic too My solution is here https://github.com/AdamClements/countdown/blob/master/src/countdown/core.clj
My solution is a little slow, depending on how tricky a problem it is, it can take from milliseconds to seconds. I ran [75 9 1 3 4] with a each target from 0 to 999 and got an average time of 824ms (including a lot where the search was exhausted). In the solvable ones it usually returns quicker than that. Like I said, this is my first attempt at logic programming, so if anyone can see how to make my solution more concise/elegant/faster, tips are much appreciated!
