First Fit Decreasing Algorithm

The First Fit Decreasing algorithm is a method for efficiently packing items into containers, like fitting books onto shelves. First, it sorts items from largest to smallest. Then, for each item, it places it into the first container that still has enough space. If none do, it starts a new container. This approach helps minimize the number of containers needed by prioritizing larger items first and filling existing spaces before creating new containers. It’s commonly used in resource allocation and logistics to optimize space and reduce waste.
