🔧 Setting Up EvoX

Install evox effortlessly via pip:

pip install evox

Note: To install EvoX with JAX and hardware acceleration capabilities, please refer to our comprehensive installation guide.

🚀 Dive Right In: Quick Start

Kickstart your journey with EvoX in just a few simple steps:

1. Import necessary modules:

import evox
from evox import algorithms, problems, workflows

2. Configure an algorithm and define a problem:

pso = algorithms.PSO(
    lb=jnp.full(shape=(2,), fill_value=-32),
    ub=jnp.full(shape=(2,), fill_value=32),
    pop_size=100,
)
ackley = problems.numerical.Ackley()

3. Compose and initialize the workflow:

workflow = workflows.StdWorkflow(pso, ackley)
key = jax.random.PRNGKey(42)
state = workflow.init(key)

4. Run the workflow:

# Execute the workflow for 100 iterations
for i in range(100):
    state = workflow.step(state)
