# selectBestEdgeAndDirection -- selects edge and direction based on highest potential for obtaining new information

## Description

By default, the solver option SelectEdgeAndDirection is set to selectRandomEdgeAndDirection; it may be changed to selectBestEdgeAndDirection as shown below. This will return an error unless the option Potential is also set.
