WEIGHT=0.5
CROSSOVER_RATE=0.8
MUTATION_RATE=0.15
NUM_TIME_SLOT=20
TRAIN_FACTOR=2
STRESS_FACTOR=1
CONST_RATE=0.0

To run, execute:

# debug mode
cargo run -- [path to csv test file]

# release-lto mode (best performance)
cargo run --profile release-lto -- [path to csv test file]

Output log is formatted in structured JSONL format. Use a tool like jq to extract relevant data.
