Wang Landau flat histogram bias. https://doi.org/10.1103/PhysRevLett.86.2050 https://doi.org/10.1063/1.1615966

Arguments

• min_flatness : Number of flatness checks required for completion.

• add_to_ln_probability : The initial amount to add to the natural log of the macrostate probability upon visiting that state (default: 1.0).

• reduce_ln_probability : Reduce the amount to add to the natural log of the macrostate probability by multiplcation of this factor upon reaching a sufficiently flat histogram (default: 0.5).

• flatness_threshold : The visited states histogram is determined to be flat when the percentage between minimum visisted states and average reaches this threshold (default: 0.8).

• min_visit_per_macro: The minimum number of visits for each macrostate required during flatness check (default: 10^3).
