%description
Algorithms for solving selective k-means problem, which is defined as
finding k rows in an m x n matrix such that the sum of each column minimal
is minimized. In the scenario when m == n and each cell value in matrix is
a valid distance metric, this is equivalent to a k-means problem. The
selective k-means extends the k-means problem in the sense that it is
possible to have m != n, often the case m < n which implies the search is
limited within a small subset of rows. Also, the selective k-means extends
the k-means problem in the sense that the instance in row set can be
instance not seen in the column set, e.g., select 2 from 3 internet
service provider (row) for 5 houses (column) such that minimize the
overall cost (cell value) - overall cost is the sum of the column minimal
of the selected 2 service provider.
