# Revisiting the Balanced Induced Subgraph Polytope

## Resumo

A signed graph G is a triple G = (V, E, s) where V is the vertex set, E is the set of undirected edges and s : E → {+, −} is a function that assigns a sign to each edge in E. Thus, E can be partitioned in two disjoint sets E + and E − , such that E + = {e ∈ E : s(e) = +} and E − = {e ∈ E : s(e) = −} and E + ∪ E − = E. We allow multiple edges in G as long as they have different signs. For convenience, denote by E + ∩ E − the set of multiple edges in E[1]. [...]
