Consecutive ones property
WebThe consecutive ones test is extended to a test for interval graphs using a recently discovered fast recognition algorithm for chordal graphs. All of these algorithms require a number of steps linear in the size of their input. Webcalled Simultaneous Consecutive-ones Property (SC1P). The largest submatrix dense in 1 would lie on the upper triangu-lar area of the permutated matrix, and its location was deter-mined based on a geometric segmentation of a triangular. We compared MEBF with other state of the art approaches on data scenarios with different density and noise ...
