PAPILO(1)

✨ NAME ✨

papilo — your new bestie that presolves linear programming problems 💅 like it literally gets rid of the messy parts before the real work even starts.

🦋 SYNOPSIS 🦋

papilo presolve [options]

papilo solve [options]

papilo postsolve [options]

Three modes, three moods, one icon. Pick your era. 👑

🎀 PRESOLVE OPTIONS 🎀

This is the glow-up phase, bestie. Feed it a problem, it hands you back a smaller one. Obsessed.

• -f FILE, --file=FILE — the instance file, aka the problem you're bringing to the group chat.
• -a TYPE, --arithmetic-type=TYPE — pick your math flavor: "d" for double precision, "q" for quad precision, and "r" for exact rational arithmetic. Choose wisely, it's giving commitment.
• -v FILE, --postsolve-archive=FILE — where to write the postsolve archive filename. Future you will need this, no cap.
• -r FILE, --reduced-problem=FILE — filename for the reduced problem. The smaller, sleeker version of your problem. Main character energy tbh.
• -p FILE, --parameter-settings=FILE — filename for presolve parameter settings.
• --print-params — prints out all the possible parameters for presolving. Like a menu but for nerds 🍓
• -t -N, --threads=N — set the number of threads. More threads = more girlies working in parallel ✨

🔥 SOLVE OPTIONS 🔥

Everything from presolve plus the solver goodies. This is where we actually eat. 😭

• -f FILE, --file=FILE — the instance file.
• -a TYPE, --arithmetic-type=TYPE — "d" for double precision, "q" for quad precision, and "r" for exact rational arithmetic.
• -v FILE, --postsolve-archive=FILE — filename for the postsolve archive.
• -r FILE, --reduced-problem=FILE — filename for the reduced problem.
• -p FILE, --parameter-settings=FILE — filename for presolve parameter settings.
• --print-params — print possible parameters for presolving.
• -t -N, --threads=N — set number of threads.
• -u FILE, --reduced-solution=FILE — filename for the solution of the reduced problem.
• -l FILE, --solution=FILE — filename for the solution. The moment we've all been waiting for 🫶
• --dualsolution=FILE — filename for the dual solution.
• -c FILE, --reducedcosts=FILE — filename for reduced costs.
• -w FILE, --basis=FILE — filename for basis information.
• -o VALUE, --reference-objective=VALUE — the correct objective value, used for validation. Lowkey the answer key 👀
• -x FILE, --soplex-settings=FILE — SoPlex settings file.
• --tlim LIMIT — time limit for the solver, and yes, that includes presolve time. The clock is ticking bestie, it counts everything. ⏰
• --print-stats — print detailed solver statistics. Numbers, numbers, numbers, slay.

💜 POSTSOLVE OPTIONS 💜

The comeback arc. You solved the reduced problem, now let's map it all back to the original. Reverse uno card, but make it math. 🌀

• -f FILE, --file=FILE — the instance file.
• -a TYPE, --arithmetic-type=TYPE — "d" for double precision, "q" for quad precision, and "r" for exact rational arithmetic.
• -v FILE, --postsolve-archive=FILE — filename for the postsolve archive.
• --dual-reduced-solution=FILE — filename for the dual solution of the reduced problem.
• --cost-reduced-solution=FILE — filename for the reduced costs of the reduced problem.
• --basis-reduced-solution=FILE — filename for the basis of the reduced problem.
• -u FILE, --reduced-solution=FILE — filename for solution of the reduced problem.
• -l FILE, --solution=FILE — filename for solution.
• --dualsolution=FILE — filename for dual solution.
• -c FILE, --reducedcosts=FILE — filename for reduced costs.
• -w FILE, --basis=FILE — filename for basis information.
• -o VALUE, --reference-objective=VALUE — correct objective value for validation.
• -b FILE, --validate-solution=FILE — the optimal solution, for validation. Proof or it didn't happen 💅

ok that's literally the whole page, no notes, go run it 🌈

and that's a wrap on papilo(1) — that's the entire footer, no version, no date, just the flex. byeeee 🎀💖✨
