extends java.lang.Object

Static class wrapping SPARSE variants of LPMatrix The internal MIP matrix is represented by a hashmap from a pair of coordinates to a value. Setting a value in this matrix is O(log N), while reading a value is amortized O(1). When adjusting a value, the method adjustMat(r, c, v) is recommended over setMat(r,c, getMat(r,c) + v).
