International Journal of Swarm Intelligence and Evolutionary Computation is an International Open Journal presents updated knowledge on Genetic Algorithm, Artificial Intelligence, Evolutionary Computation and the content published under tree topology is Peer reviewed. Swarm Intelligence and Computational Intelligence play a critical role in Robotics therefore, journal continuously publishing thematic Peer reviewed issues related to tree topology or information technology. A tree topology is a collection of star topology is arranged in hierarchical order. Different hierarchy is arranged in such a way that it should provide greater control and easier troubleshooting. In the simplest form only hub devices connect directly to the tree bus. we consider an active hub and a passive hub with n computer systems which are connected to the hub. By using Markov process, supplementary variable technique and Laplace transformation the transition state probabilities, up and down state probabilities, reliability and mean time to failure of the designed tree topology network should be evaluated. PrimeOA Publications Journals are known for their high impact factor journals and a section of PrimeOA Publications journals are indexed in the world-renowned science database like Medline, PubMed Central, Obscure and Scopus. PrimeOA Publications acquired as many as 40 reputed journals such as Oral Health and Dental Management and Molecular Genetic Medicine and others.

PrimeOA Publications organizes over 100 Scientific Conferences all over the globe annually with the support from various scientific associations and 20,000 editorial board members. Since its inception, PrimeOA Publications International has focused on meeting the needs of the scientific community, through strong tie-up with business and industry, while at the same time accomplishing international benchmarks and accreditation standards.
