This is almost like providing two images, but at a significantly smaller total size. At the extremes, the alternate image is handcuffed to the base image to a degree - but with proper encoding it provides tremendous latitude to derive a high quality alternative version of the same scene (this...
An optimization problem can be solved using Greedy if the problem has the following property: at every step, we can make a choice that looks best at the moment, and we get the optimal solution to the complete problem. Backtracking Backtracking is an algorithmic technique for solving problems ...
