query-complexity

A toolkit for teaching, learning, and doing research in Boolean function analysis. Fourier analysis, property testing, query complexity, hypercontractivity, pseudorandomness, and more

Framework for empirically exploring query complexity questions

The project applied database principles to a real-world mental health problem, emphasizing reliable data management, and showcased practical solutions to mental health challenges.

Determine in one query whether a 3-bit Boolean function is constant or balanced (oracle: f = x₀ ⊕ x₁ ⊕ x₂).

GraphQL operation guard for a supplied AST: fragment-aware depth limit with cycle guard, per-field complexity scoring, operation allowlist/denylist, and introspection blocking. graphql-js is optional — accepts its document shape structurally, zero hard dependencies.

Exact computational verification for memory under unknown future access

Analyze and limit the cost of GraphQL queries using configurable field costs
