# `Jido.Evolve.Crossover`
[🔗](https://github.com/agentjido/jido_evolve/blob/v1.0.0/lib/jido_evolve/protocols/crossover.ex#L1)

Protocol for crossover operations between two parent entities.

Crossover combines genetic material from two parents to create offspring,
introducing diversity while preserving beneficial traits from both parents.

## Example

    defmodule MyCustomCrossover do
      @behaviour Jido.Evolve.Crossover

      @impl true
      def crossover(parent1, parent2, _config) do
        # Simple single-point crossover for strings
        if String.length(parent1) > 0 and String.length(parent2) > 0 do
          point = :rand.uniform(min(String.length(parent1), String.length(parent2)))
          child1 = String.slice(parent1, 0, point) <> String.slice(parent2, point, String.length(parent2))
          child2 = String.slice(parent2, 0, point) <> String.slice(parent1, point, String.length(parent1))
          {child1, child2}
        else
          {parent1, parent2}
        end
      end
    end

# `crossover`

```elixir
@callback crossover(parent1 :: any(), parent2 :: any(), config :: map()) :: {any(), any()}
```

Performs crossover between two parent entities to produce two offspring.

## Parameters

- `parent1` - First parent entity
- `parent2` - Second parent entity  
- `config` - Configuration map that may contain crossover-specific parameters

## Returns

A tuple `{child1, child2}` containing two offspring entities.
