A spatial branch-and-cut method for nonconvex QCQP with bounded complex variables
We develop a spatial branch-and-cut approach for nonconvex quadratically constrained quadratic programs with bounded complex variables (CQCQP)....

Finding vibrations of inclined cable structures by approximately solving governing equations for exterior matrix
In this paper, how to compute the eigenfrequencies of the structures composed of a series of inclined cables is shown. The physics of an inclined...

Models and Representations
In this chapter we give a survey on methods that are used nowadays to describe spatial displacements and other transformations. Therefore, point...

Minimum penalty for constrained evolutionary optimization
Penalty function methods are popular in dealing with the constrained optimization problems. How to choose reasonable penalty coefficients is a...

High order finite difference methods on non-uniform meshes for space fractional operators
In the past decades, the finite difference methods for space fractional operators develop rapidly; to the best of our knowledge, all the existing...

Helix surfaces in the Berger sphere
We characterize helix surfaces in the Berger sphere, that is surfaces which form a constant angle with the Hopf vector field. In particular, we show...

Advanced particle swarm assisted genetic algorithm for constrained optimization problems
A novel hybrid evolutionary algorithm is developed based on the particle swarm optimization (PSO) and genetic algorithms (GAs). The PSO phase...

Partition of a planar graph with girth 6 into two forests with chain length at most 4
We prove that the vertex set of every planar graph with girth at most 6 can be partitioned into two subsets each of which generates a forest in which...

Combining Clustered Adaptive Multistart and Discrete Dynamic Convexized Method for the Max-Cut Problem
Given an undirected graph with edge weights, the max-cut problem is to find a partition of the vertices into two subsets, such that the sum of the...

Serial Group Rings of Finite Groups. p-nilpotency
It is proved that if F is an arbitrary field of characteristic p and G is a finite p-nilpotent group with a cyclic p-Sylow subgroup, then the group...

Cyclic Sieving for Generalised Non-crossing Partitions Associated with Complex Reflection Groups of Exceptional Type
We prove that the generalised non-crossing partitions associated with well-generated complex reflection groups of exceptional type obey two different...

Monotone operators on Gödel logic
We consider an extension of Gödel logic by a unary operator that enables the addition of non-negative reals to truth-values. Although its...
