Accurate virus genotyping and the detection of recombinant strains are of crucial importance for understanding viral evolution as well as the design of potential vaccines and treatment strategies. A very accurate tool for detecting recombinations in genomic HIV-1 sequences is jpHMM (jumping profile Hidden Markov Model). For a given sequence, it predicts recombination breakpoints and assigns a p...

We compare the behavior of a GA with and without crossover. A simple GA with crossover can have two stable fixed points (bistability) on the single-peak landscapes for string lengths at least 8. There are catastrophic transitions from one to two and back to one stable fixed point as the mutation rate increases. Crossover also causes the fixed-point population distribution to change. For a fixed...

The thermal transition accompanied by the variation of the molecular volume in nanoparticles of spin-crossover materials has been studied on the basis of microscopic Ising-like model solved using Monte Carlo methods. For considered model, we examined the spin-crossover phenomenon with applied hydrostatic pressure and thus was shown the possibility to shift transition temperature toward its room...

The Commonality-Based Crossover Framework has been presented as a general model for designing problem specific operators. Following this model, the Common Features/Random Sample Climbing operator has been developed for feature subset selection--a binary string optimization problem. Although this problem should be an ideal application for genetic algorithms with standard crossover operators, exp...

In this short paper, we propose a new multi-fractal flow model, aiming to provide a possible explanation for the crossover phenomena that appear in the estimation of Hurst exponent for network traffic. It is shown that crossover occurs if the network flow consists of several components with different Hurst components. Our results indicate that this model might be useful in network traffic model...

In this contribution, we summarize our recent studies on the chiral invariant mass and condensates in neutron star matter. We construct a unified equations of state assuming crossover phase transition from hadronic matter described by parity doublet model to quark an Nambu--Jona-Lasinio type model. first show that is constrained be $600\,\mbox{MeV}\, \lesssim\, m_0 \,\lesssim \, 900\,\mbox{MeV}...

In this paper, I present the theoretical results obtained for Bentley’s genetic algorithm, which is used in CAD system to generate 3D-solids designs. The Vose-like-Markov-chain model for the Bentley’s GA is proposed. The transition matrices are found and the ergodity of the Markov chain and the asymptotic correctness in the probabilistic sense are shown by using the model. The microscopic Exact...

Crossover youth includes any youth who has experienced maltreatment and also has engaged in delinquent activity. Prior studies indicate that crossover youth have higher rates of reoffending than delinquent youth without a history of child welfare involvement. The higher rates of reoffending among crossover youth are of concern given the exorbitant cost of providing services within the juvenile ...
