LEMON contains three algorithms for solving the minimum mean cycle problem:

- \ref Karp "Karp"'s original algorithm \ref amo93networkflows,


			




	
	467
	
		
- \ref KarpMmc Karp's original algorithm \ref amo93networkflows,


			




	476
	468
	
		
  \ref dasdan98minmeancycle.


			




	477
	
	
		
- \ref HartmannOrlin "Hartmann-Orlin"'s algorithm, which is an improved


			




	
	469
	
		
- \ref HartmannOrlinMmc Hartmann-Orlin's algorithm, which is an improved


			




	478
	470
	
		
  version of Karp's algorithm \ref dasdan98minmeancycle.


			




	479
	
	
		
- \ref Howard "Howard"'s policy iteration algorithm


			




	
	471
	
		
- \ref HowardMmc Howard's policy iteration algorithm


			




	480
	472
	
		
  \ref dasdan98minmeancycle.


			




	481
	473
	
		

			




	482
	
	
		
In practice, the Howard algorithm proved to be by far the most efficient


			




	483
	
	
		
one, though the best known theoretical bound on its running time is


			




	484
	
	
		
exponential.


			




	485
	
	
		
Both Karp and HartmannOrlin algorithms run in time O(ne) and use space


			




	486
	
	
		
O(n<sup>2</sup>+e), but the latter one is typically faster due to the


			




	487
	
	
		
applied early termination scheme.
