24

A solver for the 24 card game. https://ayz.ai/24

The objective of the game is to find a way to combine four positive integers using arithmetic operations to obtain a target (the number 24). Exponentiation is supported.

Things to improve:

• more deduplication of solutions
• fix excessive cloning of Ops in Card
• better serialization from solve24 across WebAssembly ABI
• suppport factorials

Usage

To compile twentyfour-wasm for the frontend, run the following from the project root:

cargo build -p twentyfour-wasm --release --target wasm32-unknown-unknown
wasm-bindgen target/wasm32-unknown-unknown/release/twentyfour_wasm.wasm --out-dir frontend/pkg

cd frontend
pnpm build
