I understand how a preorder can be interpreted as a category (reflexivity translating into identity morphisms and transitivity to associativity). But now I want to understand the category of all preorders, Preord. Here, the morphisms are the monotone/order-preserving maps.
Take two preorders, $(X...
An article on hash functions has this suggestion for making a good hashing function:
Multiplication Method (Cormen). Choose m to be a power of 2. Let A be some random-looking real number. Knuth suggests M = 0.5*(sqrt(5) - 1).
I'm a big fan of Professor Knuth (who isn't, of course), so I was cur...
Nino sells on average three cell phones more than Will. At the end of the day, they both receive $35.00$ together for the day's sales. The store manager finds that: If Will sold at price W the number of cell phones Nino sold, he would receive $24.00$. Nino would receive $12.50$ if he sold at pri...
