conjecture40

Specification

WOWII [Conjecture 40](http://cms.dt.uh.edu/faculty/delavinae/research/wowII/) For a nontrivial connected graph `G` the size `f(G)` of a largest induced forest satisfies `f(G) ≥ ceil((p(G) + b(G) + 1)/2)` where `p(G)` is the path cover number and `b(G)` is the largest induced bipartite subgraph size.
