bqpjson

release:

dev status:

bqpjson is a minimalist python package for working with bqpjson data files, a json-based encoding of binary quadratic programs. A detailed description of the bqpjson data format is available here.

The package can be installed via:

pip install bqpjson

The bqpjson toolset includes:

• bqpjson - python tools for the validation and transformation of bqpjson data (documentation)

• bqpjson-schema.json - a JSON-Schema for bqpjson data files

• spin2bool - a command line tool for converting a bqpjson data files between the spin and boolean variable spaces

• bqp2qh - a command line tool for converting bqpjson data files into qubist compatible hamiltonians

• bqp2qubo - a command line tool for converting bqpjson data into qubo data

• bqp2mzn - a command line tool for converting bqpjson data into a minizinc model

• bqp2hfs - a command line tool for converting bqpjson data into hfs data
