This is the first of the larger example problems. The constraints are derived from this set of "chemical reactions": 157 ORE => 5 NZVS 165 ORE => 6 DCFZ 44 XJWVT, 5 KHKGT, 1 QDVJ, 29 NZVS, 9 GPVTF, 48 HKGWZ => 1 FUEL 12 HKGWZ, 1 GPVTF, 8 PSHF => 9 QDVJ 179 ORE => 7 PSHF 177 ORE => 5 HKGWZ 7 DCFZ, 7 PSHF => 2 XJWVT 165 ORE => 2 GPVTF 3 DCFZ, 7 NZVS, 5 HKGWZ, 10 PSHF => 8 KHKGT -Matt > On Dec 19, 2019, at 3:45 AM, Michael Hennebry <[email protected]> wrote: > > On Wed, 18 Dec 2019, Matthew Keeter wrote: > >> Ah, I just realized that you only see Part 2 if you're logged in and have >> solved Part 1. >> >> The goal of Part 2 is to maximize production of the FUEL element, starting >> with 1 trillion >> units of ORE; that's the problem that I'm solving in my LP file. > > That helps some. > I'm seeing the 1 trillion now. > Where is the other data? > >> Since each reaction occurs an integer number of times (and both consumes and >> produces an integer number of reagents / products), the answer should be an >> integer. > > 82,892,753.14 was a joke, son. > > -- > Michael [email protected] > "Sorry but your password must contain an uppercase letter, a number, > a haiku, a gang sign, a heiroglyph, and the blood of a virgin." > -- someeecards
