(algorithm)
Definition: A polyphase merge which seeks to minimize the number of merge passes by allocating output runs of each pass to the various output files. Since polyphase merging must have a different number of runs in each file to be efficient, one seeks the optimal way of selecting how many runs go into each output file. A series of kth order Fibonacci numbers is one way to select the number of runs.
