Enum argmin::solver::simulatedannealing::SATempFunc

Temperature functions for Simulated Annealing.

Given the initial temperature t_init and the iteration number i, the current temperature t_i is given as follows:

• SATempFunc::TemperatureFast: t_i = t_init / i
• SATempFunc::Boltzmann: t_i = t_init / ln(i)
• SATempFunc::Exponential: t_i = t_init * 0.95^i
• SATempFunc::Custom: User provided temperature update function which must have the function signature &Fn(init_temp: f64, iteration_number: u64) -> f64

Variants

TemperatureFast

t_i = t_init / i

Boltzmann

t_i = t_init / ln(i)

Exponential(f64)

t_i = t_init * x^i

Custom(Box<dyn Fn(f64, u64) -> f64>)

User-provided temperature function. The first parameter must be the current temperature and the second parameter must be the iteration number.
