This research investigates the performance of various different permutation generation algorithms and how they can be optimised to improve execution time. Feel free to use the source code, which implements 5 different methods of permutation generation.

Example Usage

$ g++ -o algo main.cpp
$ ./algo
*** Not enough arguments
Usage: ./algo [algorithm-id = 5,6,7,8,9] [order=1...n] [options]
	-t	 Print out time information
	-s	 Test sorting algorithm
The above modes are mutually exclusive
$ ./algo 5 3
Generating permutations using algorithm 5: Slow Recursive order 3
     0:    1,    2,    3
     1:    1,    3,    2
     2:    2,    1,    3
     3:    2,    3,    1
     4:    3,    1,    2
     5:    3,    2,    1
