Methods

impl SimulatedAnnealing

pub fn new(init_temp: f64) -> Result<Self, Error>

Constructor

Parameter:

• init_temp: initial temperature

pub fn temp_func(self, temperature_func: SATempFunc) -> Self

Set temperature function to one of the options in SATempFunc.

pub fn stall_accepted(self, iter: u64) -> Self

The optimization stops after there has been no accepted solution after iter iterations

pub fn stall_best(self, iter: u64) -> Self

The optimization stops after there has been no new best solution after iter iterations

pub fn reannealing_fixed(self, iter: u64) -> Self

Start reannealing after iter iterations

pub fn reannealing_accepted(self, iter: u64) -> Self

Start reannealing after no accepted solution has been found for iter iterations

pub fn reannealing_best(self, iter: u64) -> Self

Start reannealing after no new best solution has been found for iter iterations
