JuMP, in Julia: https://github.com/JuliaOpt/JuMP.jl/blob/master/examples/basic.jl https://github.com/JuliaOpt/JuMP.jl/blob/master/examples/bas... It's rapidly displacing proprietary DSL's like AMPL and GAMS in operations research. Neither of those happen to be embedded in a host language, they're special-purpose. Though there are comparable tools out there embedded in Python or Matlab, they don't perform as well as JuMP or the special-purpose tools.
