Inspired by observing fireworks explosion, a novel swarm intelligence algorithm, called Fireworks Algorithm (FA), is proposed for global optimization of complex functions. In the proposed FA, two types of explosion (search) processes are employed, and the mechanisms for keeping diversity of sparks are also well designed. In order to demonstrate the validation of the FA, a number of experiments ...

Changes in U.S. fireworks laws have allowed younger children to purchase fireworks. In addition, the changes have allowed individuals to purchase more powerful fireworks. The purpose of this study is to examine the epidemiology of pediatric firework-related burn injuries among a nationally representative sample of the United States for the years 2006 to 2012. We examined inpatient admissions fo...

We investigate the effectiveness of approximation strategy in a surrogate-assisted fireworks algorithm, which obtains the elite from approximate fitness landscape to enhance its optimization performance. We study the effectiveness of approximation strategy from the aspects of approximation method, sampling data selection method and sampling size. We discuss and analyse the optimization performa...

The effects of the burning of fireworks on air quality in Beijing was firstly assessed from the ambient concentrations of various air pollutants (SO2, NO2, PM2.5, PM10 and chemical components in the particles) during the lantern festival in 2006. Eighteen ions, 20 elements, and black carbon were measured in PM2.5 and PM10, and the levels of organic carbon could be well estimated from the concen...

Human activities are a key driver of air pollution, so it is hardly surprising that celebrations affect air quality. The use of fireworks contributes to high particulate concentrations in many parts of the world, with the Chinese Lunar New Year (spring festival) particularly noticeable, as firecrackers are traditionally used to drive off evil spirits. Fireworks lead to short-term peaks in the c...

PURPOSE To evaluate the epidemiological characteristics and outcomes of ocular injuries resulting from the use of firecrackers during the Diwali festival in all age groups. MATERIALS AND METHODS A single-center, retrospective, hospital-based case series presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in North India during the 5 days of Diwali festival...

The main goal of this paper is to improve the performance of the Fireworks Algorithm (FWA). To improve the performance of the FWA we propose three modifications: the first modification is to change the stopping criteria, this is to say, previously, the number of function evaluations was utilized as a stopping criteria, and we decided to change this to specify a particular number of iterations; ...
