Minimum local distance density estimation [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2016
We present a local density estimator based on first order statistics. To estimate the density at a point, $x$, the original sample is divided into subsets and the average minimum sample distance to $x$ over all such subsets is used to define the density estimate at $x$. The tuning parameter is thus the number of subsets instead of the typical bandwidth

Equilibrium clusters in suspensions of colloids interacting via potentials with a local minimum [PDF]

open access: yesCondensed Matter Physics, 2016
In simple colloidal suspensions, clusters are various multimers that result from colloid self-association and exist in equilibrium with monomers. There are two types of potentials that are known to produce clusters: a) potentials that result from the ...

Integrating Conflict Driven Clause Learning to Local Search [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2009
This article introduces SatHyS (SAT HYbrid Solver), a novel hybrid approach for propositional satisfiability. It combines local search and conflict driven clause learning (CDCL) scheme. Each time the local search part reaches a local minimum, the CDCL is

RRT*-Fuzzy Dynamic Window Approach (RRT*-FDWA) for Collision-Free Path Planning

open access: yesApplied Sciences, 2023
Path planning is an important aspect and component in the research of mobile-robot-related technologies. Many path planning algorithms are only applicable to static environments, while in practical tasks, the uncertainty in dynamic environments increases

Fourth-order elliptic problems with critical nonlinearities by a sublinear perturbation

open access: yesNonlinear Analysis, 2021
In this paper, we get the existence of two positive solutions for a fourth-order problem with Navier boundary condition. Our nonlinearity has a critical growth, and the method is a local minimum theorem obtained by Bonanno.
