5. Wiscоnsin Jоnes аnd Atlаntis [10 Pоints] As the intrepid computer scientist/аrchaeologist adventurer Wisconsin Jones, you have been researching the roots of the ancient student society OΩΘ. A recent set of discoveries have brought you deep into the Caribbean as you have possibly connected OΩΘ to the ancient, advanced civilization of Atlantis. During one dive, you discover the most remarkable tablet: It describes a problem Max Flow All or Nothing (MFAN), which is similar to the familiar problem Max-Flow. The decision version of Max-Flow problem: Given a flow network with source and sink and capacities on each edge, is there a valid flow function with a flow value of at least from to ? MFAN problem: Given a flow network with source and sink and capacities on each edge, is there a valid flow function with a flow value of at least from to where every edge has no flow or is at capacity? For example, if an edge has capacity 3, a valid flow function must send either 0 or 3 flow through . The tablet includes an incomplete reduction from MFAN to MaxFlow. What are the odds that computer scientist/archaeologist would make such a discovery! Even more incredible, etched in the corner of the tablet is the mark of the OΩΘ society with a note: “MFAN is NP-complete - use SubsetSum!” It might seem like it would be easier to find the max flow when the edges have this all-or-nothing constraint, but it seems you will show that it is actually (NP)-hard er!
