 # Ruby Algebraic Modeling System
 
-RAMS is a library for formulating and solving [Mixed Integer Linear Programs](https://en.wikipedia.org/wiki/Integer_programming) in Ruby. Currently, it only supports the [GNU Linear Programming Kit](https://www.gnu.org/software/glpk/), but more solvers are on the way.

+If you want to switch to a different solver, simply install that solver onto your system, and change the `solver` attribute on the model.

+```ruby
+m.solver = :cbc  # or...

+Additional solver arguments can be passed as though they are command line flags.
