This talk concerns primal-dual and predictor-corrector interior-point algorithms for solving symmetric cone horizontal linear complementarity problems. We use the algebraically equivalent transformation technique to introduce new algorithms. We generalize the new classes of algorithms introduced by Illés, Rigó, and Török.
