Fast Hypertree Decompositions via Linear Programming: Fractional and Generalized

Summary: Ralph computes fractional and generalized hypertree decompositions via LP randomized approximation. MILP/LP heuristics atop Korchemna et al.'s poly-time fractional approximation enable near-optimal decompositions on HyperBench and solving 500 unsolved instances.
