PQ-RRT*: An improved path planning algorithm for mobile robots
Expert systems with applications, 2020During the last decade, sampling-based algorithms for path planning have gained considerable attention. The RRT*, a variant of RRT (rapidly-exploring random trees), is of particular concern to researchers due to its asymptotic optimality.

The fault characteristics of an inverter interfaced distributed generator (IIDG) depend on its control strategy and whether it has a low voltage ride-through (LVRT) capability, which cannot be a simple equivalent to a constant power or current source ...

Let \(F/k\) be a normal extension of number fields with Galois group \(G\). If in the Brauer-Kuroda relation of the Dedekind zeta functions of intermediate fields of \(F/k\) the zeta function of \(F\) does not appear (this only depends on \(G\)), then the group \(G\) is said to be exceptional (see \textit{J. Browkin} et al. [Bull. Pol. Acad. Sci., Math.

Let α ∈ ℤ\{0}. A positive integer N is said to be an α-Korselt number (Kα-number, for short) if N ≠ α and N - α is a multiple of p - α for each prime divisor p of N. By the Korselt set of N, we mean the set of all α ∈ ℤ\{0} such that N is a Kα-number; this set will be denoted by [Formula: see text].

The travelling salesman and the PQ-tree
Mathematics of Operations Research, 1996Let D = (dij ) be the n × n distance matrix of a set of n cities {1, 2, …, n}, and let T be a PQ-tree with node degree bounded by d that represents a set Π(T) of permutations over {1, 2, …, n}. We show how to compute for D in O(2 dn 3) time the shortest travelling salesman tour contained in Π(T).

PQ Forum #20. Problems Impacting PQ Documents
Journal of Validation Technology, 2021Managers have also described problems that have negatively impacted PQ documents, problems not with validation PQ documents per se, but associated problems affecting PQ documents. These events damaged PQ credibility, and sometimes necessitated repetition of a previously completed validation. These experiences demonstrate the need for proactive measures
