The inverse k-max combinatorial optimization problem [PDF]
Classical combinatorial optimization concerns finding a feasible subset of a ground set in order to optimize an objective function. We address in this article the inverse optimization problem with the k-max function. In other words, we attempt to perturb

On Column-Convex and Convex Carlitz Polyominoes [PDF]
In this paper, we introduce and study {\it Carlitz polyominoes}. In particular, we show that, as $n$ grows to infinity, asymptotically the number of \begin{enumerate} \item column-convex Carlitz polyominoes with perimeter $2n$ is \beq \frac{9\sqrt{2}(14+3\sqrt{3})}{2704\sqrt{πn^3}}4^n.

Triangulability of convex graphs and convex skewness [PDF]
Suppose [Formula: see text] is a subgraph of a convex complete graph [Formula: see text] and [Formula: see text] contains no boundary edge of [Formula: see text] and [Formula: see text]. We determine necessary and sufficient conditions on [Formula: see text] such that [Formula: see text] admits a triangulation.

Experimental and Numerical Investigation of the Heat Transfer of Honeycomb-Structured Tubes
Tube bundle recuperators are generally designed to operate with smooth tubes. Structured tubes can be used to increase the efficiency of recuperators. Compared to smooth tubes, the surface for heat transfer is increased and thus heat transfer is enhanced.

Some q-Fractional Estimates of Trapezoid like Inequalities Involving Raina’s Function
In this paper, we derive two new identities involving q-Riemann-Liouville fractional integrals. Using these identities, as auxiliary results, we derive some new q-fractional estimates of trapezoidal-like inequalities, essentially using the class of ...

An Adaptive Projection Gradient Method for Solving Nonlinear Fractional Programming
In this study, we focus on solving the nonlinear fractional optimization problem in which the numerator is smooth convex and the denominator is smooth concave.

An assessment of mood or emotion is important in developing mental health measures, and facial expressions are strongly related to mood or emotion. This study thus aimed to examine the relationship between levels of negative mood and characteristics of ...

Advances in Ostrowski-Mercer Like Inequalities within Fractal Space
The main idea of the current investigation is to explore some new aspects of Ostrowski’s type integral inequalities implementing the generalized Jensen–Mercer inequality established for generalized s-convexity in fractal space.

AbstractWe present a generalization of the notion of neighborliness to non-polyhedral convex cones. Although a definition of neighborliness is available in the non-polyhedral case in the literature, it is fairly restrictive as it requires all the low-dimensional faces to be polyhedral.
