v0.3.0 — CartPole Baseline Successfully Reproduced

##Overview

v0.3.0 marks a major milestone in the project by successfully reproducing strong PPO baseline performance on CartPole-v1.

The agent now demonstrates stable learning behaviour and consistently achieves high evaluation rewards.

Key Achievements

• successful reproduction of CartPole baseline performance
• evaluation rewards consistently reaching high values (>150-250)
• peak performance approaching environment maximum (~500)
• stable learning dynamics across extended training

Improvements

• extended training duration (500k timesteps)
• tuned learning rate and entropy coefficient
• improved evaluation stability with multiple episodes
• refined experiment tracking and plotting

Results

The PPO implementation now produces reliable and reproducible results, demonstrating correct and effective learning behaviour.

Next steps

• benchmark performance against Stable-Baseline3
• extend experiments to more complex environments
• add detailed report and analysis
