bqpjson 0.5.3

Description:

bqpjson 0.5.3

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

An example of bqpjson data:

{"coeff": -0.7, "id": 6}
],
"metadata": {},
"offset": 0.0,
"quadratic_terms": [
{"coeff": -0.2, "id_head": 4, "id_tail": 2},
{"coeff": 1.5, "id_head": 6, "id_tail": 2}
],
"scale": 1.0,
"variable_domain": "spin",
"variable_ids": [2,4,6],
"version": "1.0.0"
}
