 ## **Introduction**
 [MacroPlacement](../../) is an open, transparent effort to provide a public, baseline implementation of [Google Brain’s Circuit Training](https://github.com/google-research/circuit_training) (Morpheus) deep RL-based placement method.  In this repo,  we aim to achieve the following.
