Tutorial clarifies obscure 1971 algorithm for minimum directed spanning trees

By PulseAugur Editorial · [1 sources] ·

This paper provides a tutorial on Bock's 1971 algorithm for minimum-cost arborescence problems. It clarifies the algorithm's original Algol presentation, which is considered obscure, by offering a structured reformulation. This reformulation replaces temporary label changes with explicit state components, ensuring the preservation of Bock's original candidate choices and solution. AI

    A gentle tutorial on Bock's algorithm for minimum directed spanning trees with a structured reformulation

    arXiv:2603.27530v2 Announce Type: replace Abstract: Bock's 1971 algorithm is an exact primal--dual method for the minimum-cost arborescence problem, but its Algol presentation obscures the interaction of its maintained arrays and label-directed control flow. We provide a self-con…
