# BfsInstance:solver_setup(+OptSense, +Solver)

Setup a bfs solver tree for bfs instance BfsInstance.
*OptSense*
- Optimisation direction: min or max
*Solver*
- Node relaxation solver

## Description

Setup a new solver tree for the bfs instance BfsInstance. The tree
will be associated with BfsInstance; BfsInstance must not already
have a solver tree associated with it. Once the solver tree is setup,
it can be optimised via solve/1.

This is a simplified version of solver_setup/3, it is equivalent to
calling solver_setup/3 with the following default options:

solver_setup(OptSense, Solver, [])
