Example of Best Fit Memory allocation WebWorst Fit: As best fit leaves many small, useless holes it might be a good idea to always use the largest hole available. The idea is that splitting a large hole into two will leave a large enough hole to be useful. It has been shown that this algorithm is not very good either.
