FPL Builder

The tool solves lineup optimization for fantasy Premier League managers. Users provide a player pool with fields such as name, position, team, cost, and projected_points, plus constraints including squad_size, budget, and maximum transfers. The system outputs optimized lineups that respect formation rules (for example 3-4-3 or 3-5-2) and budget limits, enabling repeatable, data-driven selection instead of ad hoc guessing.

Conceptually, each player is an item with a cost and a value (projected_points). The algorithm enforces position quotas and total cost, then ranks feasible lineups by projected_points, using tie-breakers such as cost efficiency and fixture weight. Optional scenario analysis lets users compare multiple formations or budget constraints side-by-side, with results exported as structured data for reporting or tooling pipelines.

Who benefits and typical workflows: individual fantasy managers, analysts producing content, and small fantasy teams seeking reproducible methods. Core features include data ingestion, constraint-based optimization, multi-formation support, scenario comparisons, and export options (CSV/JSON). Use cases include pre-draft lineup drafting, weekly rotation planning, and what-if analyses during injuries or form changes.

Unique value and differentiators: deterministic optimization with configurable weighting (points, value per cost, fixture difficulty), transparent rules, and easy integration into data workflows. The tool focuses on domain-specific FPL constraints, avoids opaque heuristics, and produces auditable top-k lineups for decision making.
