Best FitComputingBest Fit A resource allocation scheme (usually for memory). Best Fit tries to determine the best place to put the new data. The definition of 'best' may differ between implementations, but one example might be to try and minimize the wasted space at the end of the block being allocated - i.e. use the smallest space which is big enough. By minimizing wasted space, more data can be allocated overall, at the expense of a more time-consuming allocation routine. Compare First Fit. (1997-06-02).

Best fitStatisticsThe term is used especially in relation to the fitting of theoretical distributions to observation and the fitting of regression lines. The excellence of the fit is often measured by some criterion depending on the squares of differences between observed and theoretical value, and if the criterion has a minimum value the corresponding fit is said to be best.
