Solution to OpenAI Gym CartPole-v0 using hill climbing

Problem statement

https://gym.openai.com/envs/CartPole-v0

A pole is attached by an un-actuated joint to a cart, which moves along a frictionless track. The system is controlled by applying a force of +1 or -1 to the cart. The pendulum starts upright, and the goal is to prevent it from falling over. A reward of +1 is provided for every timestep that the pole remains upright.

Clustering

Uses of clustering

• Summarization: Apply algo on cluster prototypes instead of actual data if actual data is large.

• Compression: Don't store all attributes of all objects. Store all attributes for cluster prototypes.
