See plansDeeper BFS (Breadth-First Search) directly fights the branching-cost derivation, leading to unacceptable latency. The disagreement should be reframed: the goal is not deeper traversal, but smarter traversal. You should implement ranked traversal at the same depth rather than unranked traversal. This can be achieved by pruning or ranking the frontier after each hop, or by narrowing the search space via community structure before the expansion begins.
