Connect and run

Clone this repo

git clone https://github.com/hotamago/reevo.git

Example command

python main.py problem=tsp_aco init_pop_size=30 pop_size=10 max_fe=100 timeout=10 algorithm=hota llm_client=langflow llm_client.api_url="http://localhost:7860" llm_client.flow_id="d240dea0-b62d-488b-8866-4a1d13c7d9d7"

Explain:

• problem = name of problem to solve (check name in problems folder)
• init_pop_size = initial population size
• pop_size = population size
• max_fe = maximum function evaluations
• timeout = timeout in seconds
• algorithm = algorithm to use (e.g., hota, reevo)
• llm_client = language model client (e.g., langflow, openai)
• llm_client.api_url = API URL of langflow
• llm_client.flow_id = flow ID in langflow
