Intuition: Want to avoid too large of a policy update
- Smaller policy updates more likely to converge to optimal
- Falling "off the cliff" might mean it's impossible to recover
How we solve this: Measure how much policy changes w.r.t. previous, clip ratio to Failed to parse (unknown function "\varepislon"): {\displaystyle [1-\varepislon, 1 + \varepsilon]} removing incentive to go too far.
