Reviews: Multi-objective Maximization of Monotone Submodular Functions with Cardinality Constraint

The paper proposes three efficient multiobjective submodular maximization algorithms. I like this paper, and has no clear objection to the paper. The techniques (using one-pass procedure for picking the heavy elements, separating MWU and the continuous greedy) are simple and effective, and seem to be applied for more general problems. The first paragraph (many well known ...) is arguable. There are many non-submodular combinatorial optimization problems.
