CCOR in CIAS organizes a workshop entitled \u201cA class of algebraically
equivalent transformations for symmetric cone horizontal linear complementarity
problems\u201d with three speakers, Zsolt Darvay, Petra Ren\u00e1ta Rig\u00f3 and Roland T\u00f6r\u00f6k.<\/p>\n\n\n\n
The date of the workshop is: September 22, 13:00-16:00
It will be organized in a hybrid way, you can attend in person in room C.510, or connect
online via Teams.
13:00-13:30
Petra Ren\u00e1ta Rig\u00f3: New predictor-corrector interior-point algorithm with AET
function having inflection point
We present a new predictor-corrector interior-point algorithm (PC IPA) for solving P*(\u039a)-
linear complementarity problems. We use the algebraically equivalent transformation
(AET) technique in order to determine the search directions. In this method we apply the
function which has inflection point. It is interesting that the kernel corresponding to this
AET function is neither self-regular, nor eligible. We show that the iteration bound of the
algorithm matches the best known iteration bound for this type of PC IPAs given in the
literature.<\/p>\n\n\n\n
13:30-14:00
Roland T\u00f6r\u00f6k: Implementation of predictor-corrector interior-point method based on
a new AET fuction
In this presentation we show numerical results about a new predictor-corrector (PC)
interior-point algorithm (IPA) for solving sufficient linear complementarity problems. We
applied a function having inflection point on the nonlinear equation of the central path
system to define new search directions. We consider numerical results of our new method
compared to other PC IPAs that use different search directions.<\/p>\n\n\n\n
14:00-14:30 Coffee break<\/p>\n\n\n\n
14:30-16:00
Zsolt Darvay: A class of algebraically equivalent transformations for symmetric
cone horizontal linear complementarity problems
In this talk, we present a generalization of the interior-point algorithms (IPAs) introduced by
Ill\u00e9s, Rig\u00f3, and T\u00f6r\u00f6k [Unified approach of primal-dual interior-point algorithms for a new
class of AET functions, Corvinus Econ. Work. Paper. 2022\/02 (2022)]. This class of
algorithms is based on the algebraically equivalent transformation (AET) of the central
path system. We propose a modification of the class presented by Ill\u00e9s, Rig\u00f3, and T\u00f6r\u00f6k.
In the general framework of P*(\u039a)-horizontal linear complementarity problems over the
Cartesian product of symmetric cones, we prove the polynomial iteration complexity of the
new algorithms.<\/p>\n\n\n\n
