Maximum subarray problem is the method to find the contiguous subarray within a one-dimensional array of numbers which has the largest sum. The problem was originally proposed by Ulf Grenander of Brown University in 1977, as a simplified model for maximum likelihood estimation of patterns in digiti...

The [record][1] library provides the ability to create compound terms with named fields. The directive :- record/1 <spec> compiles to a collection of predicates that initialize, set and get fields in the term defined by <spec>. For example, we can define a point data structure with nam...
