QUBOLib.jl

Getting Started

Installation

julia> import Pkg; Pkg.add("QUBOLib")

julia> using QUBOLib

Example

julia> using QUBOLib

julia> QUBOLib.access() do index
           println(index)
       end

Retrieving instances

QUBOLib instances are distributed as a Julia artifact recorded in Artifacts.toml, not as checked-in data files. The artifact is downloaded from the package releases the first time QUBOLib.access needs it, then copied into a local qubolib directory for use.

The database-query examples below use SQLite.jl and DataFrames.jl directly, so add them to the active Julia project before running those examples:

julia> import Pkg; Pkg.add(["SQLite", "DataFrames"])

Use QUBOLib.access to open the local index, query the SQLite database for instance identifiers, and load the selected models from the HDF5 archive:

julia> using QUBOLib

julia> using SQLite, DataFrames

julia> model = QUBOLib.access() do index
           df = DBInterface.execute(
               QUBOLib.database(index),
               "SELECT instance FROM Instances…
