DFS Β· Lineup Optimizer + GPP Simulator

LINEUP OPTIMIZER

Build optimal DraftKings, FanDuel or Easy Office Pools lineups in the browser β€” lock & ban, cap cumulative ownership and per-player exposure, add group rules (at-least / at-most N from a set), conditional (if-A-then-B) rules, enforce uniqueness between lineups, and late-swap around golfers who have already teed off. Export to DraftKings, FanDuel, Yahoo, SuperDraft & OwnersBox. Then simulate a GPP under Single-Entry, 3-Max or Milly-Maker contest presets: draw scores from each golfer’s projection band, build an ownership-weighted field, apply that contest’s payout curve, and lead with the metric the field ignores β€” your expected duplicate count β€” alongside ROI, Cash% & first-place odds.

Rocket Classic Β· DraftKings $50K/6 Β· FanDuel $60K/6 Β· Easy Office Pools $68K/8. The optimizer maximizes total projected points under the salary cap via a greedy fill with randomized restarts (each lineup distinct, near-optimal), honoring locks, bans, ownership & exposure caps, group/conditional rules, the uniqueness floor and late-swap. The GPP simulator draws each golfer’s fantasy score from a Normal(projection, std-dev) band, builds an ownership-weighted opponent field, applies the chosen payout shape and reports ROI / Cash% / first-place odds / expected dupes.
