 The arguments to `solve` are common across all of the optimizers.
 These common arguments are:
 
-  - `maxiters` (the maximum number of iterations)
-  - `maxtime` (the maximum of time the optimization runs for)
-  - `abstol` (absolute tolerance in changes of the objective value)
-  - `reltol` (relative tolerance  in changes of the objective value)

 solver portion of the documentation and their respective documentation.
