SemiringAlgebra.jl

The doc/ directory includes a paper Novel Algebras for Advanced Analytics in Julia, which describes the motivation for this package and its design.

Example usage, see the bench() function in SemringAlgebra.jl.

julia> using Pkg; Pkg.add(PackageSpec(url = pwd())); Pkg.build()

julia> Pkg.test("SemiringAlgebra")

julia> using SemiringAlgebra

julia> SemiringAlgebra.bench(100)
