public abstract void selectPlans(CPlanMemoTable memo,
                                 ArrayList<Hop> roots)
```
    Given a HOP DAG G, and a set of partial fusions plans P, find the set of optimal, non-conflicting fusion plans P' that applied to G minimizes costs C with P' = \argmin_{p \subseteq P} C(G, p) s.t. Z \vDash p, where Z is a set of constraints such as memory budgets and block size restrictions per fused operator.
    
    Parameters:
    
    memo - partial fusion plans P
    
    roots - entry points of HOP DAG G
