Multiobjective design optimization problems require multiobjective optimization techniques to solve, and it is often very challenging to obtain high-quality Pareto fronts accurately. In this paper, the recently developed flower pollination algorithm (FPA) is extended to solve multiobjective optimization problems. The proposed method is used to solve a set of multobjective test functions and two...

Foraging pollinators can be expected to choose patches with high densities of floral resources. As a result, plants in flower-dense patches may receive higher visitation rates and pollination, hence, the pollination of one plant may be facilitated by the presence of neighbour plants. Facilitation of pollination has been predicted by theoretical models and demonstrated in some empirical studies,...

in 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for xenia or metaxenia in persian walnut. pistillate flowers of ‘jamal’, ‘chandler’, ‘hartley’ and ‘pedro’ were crossed with the pollen of ‘serr’, ‘z60’ and ‘damavand’. the pistillate flowers on each female parent were covered about one week ...

Modern optimization has in its disposal an immense variety of heuristic algorithms which can effectively deal with both continuous and combinatorial optimization problems. Recent years brought in this area fast development of unconventional methods inspired by phenomena found in nature. Flower Pollination Algorithm based on pollination mechanisms of flowering plants constitutes an example of su...

Abstract Due to weather changes, the distributed photovoltaic (PV) output power has fluctuations, seriously affecting quality of distribution network. This paper proposes a PV fluctuation suppression method based on improved Flower Pollination Algorithm (FPA) solve above problem. uses an annihilation perturbation mechanism and linear weights update pollen position, which mainly affects plants. ...

Due to the rapid increased in the day by day users for spectrum cause scarcity of it. So due to its limitation and for the effective utilization of spectrum Cognitive Radio (CR) technology came into existence. This CR consists of its four main modules, which are: Spectrum sensing, mobility, sharing and management. Among which spectrum sensing is the keystone part, as due to the dependency of ot...

BACKGROUND AND AIMS Macaranga (Euphorbiaceae) is a large genus of dioecious trees with approx. 260 species. To date, only one pollination study of the genus has reported brood-site pollination by thrips in M. hullettii. In this study, the pollination system of Macaranga tanarius is reported. METHODS The study was conducted on Okinawa and Amami Islands, Japan. Flower visitors on M. tanarius we...

Nursery pollination in Caryophyllaceae species by Hadena and Perizoma moths has been extensively described in the last few decades. Evidence across multiple pairs of species shows that such pollination systems constitute relatively specialized interactions, shifting between parasitism and mutualism depending on the presence of effective co-pollinators. In this work, we describe a new specific S...

The cluster-based routing protocols are most accepted to improve the network lifetime and to reduce the energy consumption of wireless sensor network. This paper presents the pollination based optimization algorithm also called OLEACH-C to improve the performance of LEACH-C protocol. The PBO algorithm is used for clustering in WSN. The node that has maximum remaining energy will be selected as ...
