Struct metaheuristics_nature::Solver [−][src]
pub struct Solver<F: ObjFunc>(_);
Expand description
A public API for using optimization methods.
Users can simply obtain their solution and see the result.
- The method is a type that implemented
Algorithm
. - The objective function is a type that implement
ObjFunc
. - A basic algorithm data is hold by
Context
.
This type can infer the algorithm by Setting::Algorithm
.
use metaheuristics_nature::{Rga, Setting, Solver, Task};
let s = Solver::solve(
MyFunc::new(),
Rga::default().task(Task::MinFit(1e-20)),
|_| true, // Run without callback
);
// Get the result from objective function
let ans = s.result();
// Get the optimized XY value of your function
let x = s.best_parameters();
let y = s.best_fitness();
// Get the history reports
let reports = s.reports();
Implementations
Create the task and run the algorithm, which may takes a lot of time.
Argument callback
is a progress feedback function,
returns true to keep algorithm running, same as the behavior of the while-loop.
Get the reference of the objective function.
It’s useful when you need to get the preprocessed data from the initialization process, which is stored in the objective function.
Get the best parameters.
Get the best fitness.
