Hello, I pulled in the merges made by Olly today and then :- -> Optimized the upper bound on DLH by 4 times. Have opened a PR for the same. -> Added some more optimizations to DPH to improve upper bound and also removed factor from sumpart. Have opened a new PR for this too. -> Have corrected the typo in BB2weight. -> Will finish the merging of these and PL2 and Bo1 query expansion before mid-term.
