# Run Iterative Agent on the K-Module Problem
#
# Usage: ./run_iterative.sh [iterations]
#
# Prerequisites:
#   1. Clone the agentic-code-optimization repo:
#      git clone https://github.com/ratulm/agentic-code-optimization.git
#
#   2. Set environment variables:
#      export MODEL_PROVIDER=gemini
#      export GOOGLE_API_KEY=your_key
#
#   OR for OpenRouter:
#      export MODEL_PROVIDER=openai
#      export OPENAI_API_KEY=your_openrouter_key
#      export OPENAI_API_BASE=https://openrouter.ai/api/v1
