Mutation strategies for permutation genomes.

Supports three mutation modes:

• :swap - Swap two random positions
• :inversion - Reverse a random segment
• :insertion - Remove an element and insert it elsewhere

Options

• :mode - Mutation mode (default: :swap)
• :rate - Mutation rate (default: from config)

Examples

# Swap mutation
mutate([0, 1, 2, 3, 4], 1.0, mode: :swap)
# => [0, 3, 2, 1, 4]

# Inversion mutation
mutate([0, 1, 2, 3, 4], 1.0, mode: :inversion)
# => [0, 3, 2, 1, 4]

# Insertion mutation
mutate([0, 1, 2, 3, 4], 1.0, mode: :insertion)
# => [0, 1, 3, 4, 2]
