Create a temperature function that returns the annealing temperature at a given step (iteration)

Source: R/sim_annealing.R

Supported annealing types are currently "Exponential multiplicative", "Logarithmic multiplicative", "Quadratic multiplicative" and "Linear multiplicative", each with dedicated constraints on alpha.

mk_simanneal_temp_func(T0, alpha, type = "Quadratic multiplicative")

Arguments

T0

Initial temperature at step 1 (when k=0)

alpha

Rate of cooling

type

Type of annealing protocol. Defaults to the quadratic multiplicative method which seems to perform well.

Value

Temperature at cycle k.
