- Figure: comparison of the time consumption to simulate
a two dimensional three state (S=1) ferromagnetic Ising_S spins
on a square lattice for various algorithms
(Metropolis,Me, Restricted metropolis, Med, Direct Heat Bath, DHB,
Restricted Direct Heat Bath, DHBd,
Walter Algorithm, WA,
Restricted Walter Algorithm Hasting, WAHd ).
We note that the DHB and WA are equivalent. Only the time
consumption changes. DHBd and WAHd are also equivalent.
The critical temperatures are shown by the squares
The Restricted Walter Algorithm Hasting, WAHd or the direct
Heat Bath DHBd
are the fastest algorithms at the critical temperature.
