Detailed Description

template<typename Adapter>
class Zoltan2::MatrixPartitioningProblem< Adapter >

MatrixPartitioningProblem sets up partitioning problems for the user.

The MatrixPartitioningProblem is the core of the Zoltan2 partitioning API. Based on the the user's input and parameters, the MatrixPartitioningProblem sets up a computational Model, and a Solution object. When the user calls the solve() method, the MatrixPartitioningProblem runs the algorithm, after which the Solution object may be obtained by the user.

Todo:

include pointers to examples

follow partitioning with global or local ordering

allow unsetting of part sizes by passing in null pointers

add a parameter by which user tells us there are no self edges to be removed.

- Should Problems and Solution have interfaces for returning views and for returning RCPs? Or just one? At a minimum, we should have the word "View" in function names that return views.

The template parameter is the InputAdapter containing the data that is to be partitioned.
