# MAHF BMF

A collection of common continuous benchmark functions for [MAHF](https://github.com/mahf-opt/mahf).

All functions are scaled to a domain of [-1, 1] for each dimension.

# Getting Started

Add the following to your `Cargo.toml`:

```toml
[dependencies]
mahf = { git = "https://github.com/mahf-opt/mahf" }
mahf_bmf = { git = "https://github.com/mahf-opt/mahf-bmf" }
```

Constructing a problem instance and evaluating a solution:

```rust
use mahf::problems::ObjectiveFunction;
use mahf_bmf::BenchmarkFunction;

let problem = BenchmarkFunction::sphere(/*dim: */ 30);
let x = vec![0.1; 30];
println!("f({:?}) = {:?}", x, problem.objective(&x));
```
