# BfsInstance:node_info(+Var, ?Lo, ?Hi, ?Val, ?RC)

Get or set node bounds and solution information for an individual solver problem variable Var.

Var
  A solver problem variable for solver the associated with BfsInstance
Lo
  Lower bound for Var (number)
Hi
  Upper bound for Var (number)
Val
  Solution value for Var (number)
RC
  Reduced cost for Var (number)

## Description

Retrieve or update bounds and solution information for an individual solver problem variable Var for the current open node of the search tree associated with the bfs instance BfsInstance. If Var was not already a problem variable for BfsInstance it will now be considered one. If reduced costs are available in problems involving eplex instances supplying these to the bfs solver can lead to improved pruning.
