,Combinatorial Algorithms for Rooted Prize-Collecting Walks and Applications to Orienteering and Min paths starting at a prescribed root node, so as to minimize the sum of the node visiting times. Our combinatorial algorithm allows us to sidestep the part where we solve a preflow-based LP in the LP-rounding algorithms of [.] for orienteering, and in the state-of-the-art 7.183-approximation algorit
