I'm playing around with core.logic, and have this code so far: https://gist.github.com/3981557
There are 2 people and 3 tasks. Each task has a start time (you can't start the task until this time or later), and end time (you must finish the task by this time), and a duration (how long it takes to perform the task). Time is just an integer. My answer includes 3 vectors of the form: [task-id, person-id, start-time, end-time], where person-id is the person doing the task, and start-time/end-time are when the task was done (must fall within the start and end times of the task). I have two goals: one of them ensures that the second element of each vector is a person, and the other ensures that the times are correct. Now, I want to prevent the same person from doing two tasks at the same time. In other words, for any two vectors in the result, either the person-id must be different or the start/end times must not overlap. I've tried some things (using conde, !=, and <=fd), and can't seem to get it to work. Is this easy to do? Am I going about this entire problem the wrong way? Also, how can I make time-intervalso (or any of my code) look better? It doesn't look nearly as elegant as the core.logic code I've seen elsewhere. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
