Reformulating mixed-integer quadratically constrained quadratic programs [PDF]
, 2011 It is well known that semidefinite programming (SDP) can be used to derive useful relaxations for a variety of optimisation problems. Moreover, in the particular case of mixed-integer quadratic programs, SDP has been used to reformulate problems, rather ...

An Investigation of Various Controller Designs for Multi-Link Robotic System (Robogymnast)
Knowledge, 2022 An approach to controlling the three-link Robogymnast robotic gymnast and assessing stability is proposed and examined. In the study, a conventionally configured linear quadratic regulator is applied and compared with a fuzzy logic linear quadratic ...

Optimal Monomial Quadratization for ODE Systems [PDF]
, 2021 Quadratization problem is, given a system of ODEs with polynomial right-hand side, transform the system to a system with quadratic right-hand side by introducing new variables. Such transformations have been used, for example, as a preprocessing step by model order reduction methods and for transforming chemical reaction networks.

Characterization, stability and hyperstability of multi-quadratic–cubic mappings
Journal of Inequalities and Applications, 2021 In this paper, we unify the system of functional equations defining a multi-quadratic–cubic mapping to a single equation. Applying a fixed point theorem, we study the generalized Hyers–Ulam stability of multi-quadratic–cubic mappings.

Representation and perturbations of a system of additive-quadratic functional equations [PDF]
Mathematics and Computational SciencesIn the present article, we introduce a novel multimixed additive-quadratic mapping, and then show that the system of several mixed additive-quadratic equations defining a multimixed additive-quadratic mapping can be described as one single equation.
