— The paper reviews the state-of-the-art nature inspired metaheuristic algorithms in optimization, including the Firefly algorithm, PSO algorithms and ABC algorithm. By implementing them in Matlab, we will use worked examples to show how each algorithm works. Firefly algorithm is an evolutionary optimization algorithm, and is inspired by the flashing behavior of special flies called fireflies in nature. There are some noisy non-linear mathematical optimization problems that can be effectively solved by Metaheuristic Algorithms. Firefly algorithm is one of the new metaheuristic algorithms for these optimization problems. The algorithm is inspired by the flashing behavior of fireflies. Firefly Algorithm (FA) is a recent nature inspired optimization algorithm, which simulates the flash pattern and characteristics of fireflies. It is a powerful swarm intelligence algorithm inspired by the flashing phenomenon of the fireflies. The optimization results of both PSO and Firefly are analyzed from the results obtained in Matlab and the results are used to compare both the algorithms.

INTRODUCTION
Most of the conventional or classic algorithms are deterministic. For example, the simplex method in the linear programming is deterministic. Some deterministic optimization algorithms used the gradient information, they are called the gradient-based algorithms. Firefly is a metaheuristic algorithm that is inspired by the
It has been determined that using an evolutionary approach to change within this organization could be the most appropriate choice due to the use of new technology. By using an incremental approach to developing and implementing features of the organization’s new sales technology and engaging employees in training and development, it is feasible to automate the tracking of the department’s sales and minimize additional work for both sales associates and sales management. By taking a gradual approach, the evolutionary process will help the sales team easily adopt the new processes and allow the management team to cultivate knowledge, identify major issues and improve the planning experience (1997). It is argued that managers who use this method of change recognize that sustaining organizational change is most often evolutionary instead of revolutionary, and it is believed that using evolutionary change as a process for major changes within an organization will lead to more long-term success (1997). Using these principles, this change will occur gradually in three stages following some of Kotter’s model over 6 to 12 months.

There are four different rules of heuristics in social psychology – representative heuristics, availability heuristics, anchoring and adjustment heuristics, and finally status quo heuristics. Often people employ heuristics to come to conclusions about a topic rather quickly than sitting and taking their time to go through the standard notions of problem- solving to finally make a decision. A heuristic is a judgement that may conclude in a probable answer, but may not always be the exact answer overall, or could be the wrong answer altogether. They do not take into account the base- rate of an event. A base- rate can be defined as the actual calculated number of events that happen in the total population being referenced.
Determinism claims that all events are inevitable to have certain results at the end, since conditions are met and nothing else would occur. And it could apply to everything in the universe with causal laws. With the discovering laws, we could make predictions. Over the years, there are more than one determinism been developed over time.
In GSO, each glow worm, agent, carries a light on two dimensional works space and has its own vision, called local-decision range. The luciferin level is associated with the objective value of the agent’s position. The brighter agent means that it flies to a better position (has a better objective value).The agent is only attracted by a neighbor whose luciferin intensity is higher than its own within the local decision range and then flies towards the neighbor. The local-decision range depends on the number of neighbors. While the neighbor-density is low, the range is enlarged in order to find more neighbors, otherwise the range is reduced. The agent always changes its moving direction according to which neighbor is selected. The higher luciferin level the neighbor has, the more attraction which gains. Finally, most agents willget together at the multiple locations. Briefly, the GSO involves in three main phases: luciferin update phase, movement phase, and decision range update.
Step 1: Some parameters are initialized with certain values. These parameters include operation and maintenance coefficient, number of variables, and constraints such as boundaries of variables and battery, charge and discharge efficiency, maximum number of iteration, population size or swarm size, inertia weight and its damping ratio, personal and global learning coefficient, and velocity limits.
Decision making is a process that involves an individual to make a choice between multiple options available. In an often subconscious effort to facilitate that choice, a person may use heuristics. Heuristics are general strategies to arrive at a correct conclusion (Matlin, 2013). They have been described as “mental shortcuts” to make decisions rapidly. These are adaptive, based on one’s past experiences, and often instantaneous tools one uses to produce what is hoped to be the best outcome when faced with a choice. Three of the most commonly used heuristics in the decision making process are the representative heuristic, the availability heuristic, and the anchoring and adjustment heuristic. While these
The Jakob Nielson’s 6th heuristic states that make objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate (Nielsen, J. 1995). The Jakob Nielson’s 6th heuristic, recognition rather than recall, lessens the user's memory load by creating objects, actions, and options visible. With the incorporation of the Jakob Nielson’s 6th heuristic rule, the user would not have to remember information from a part of the dialogue to the other. Instructional commands for use of a system should be visible or effortlessly retrievable whenever
What determinism means based on a philosophical level is that it is just like a philosophical kind of idea that is in every event or state of affairs. This is included in every type of human decision and action and even the inevitable and the most necessary consequence of the antecedent states of affairs. What this means is basically that Determinism is the theoretical theory that everything that happens which also incorporates everything that the person like
Benchmark functions used are minimization functions and are subdivided into the two groups i.e., unimodal and multimodal. Multimodal functions are also categorized into fixed dimension and high dimension multimodal functions. GSA is a heuristic optimization algorithm which has been gaining interest among the scientific community recently. GSA is a nature inspired algorithm which is based on the Newton’s law of gravity and the law of motion. GSA is grouped under the population based approach and is reported to be more intuitive. The algorithm is intended to improve the performance in the exploration and exploitation capabilities of a population based algorithm, based on gravity rules. However, recently GSA has been criticized for not
Nature presents suggestion to the humans in many ways. One way of such inspiration is the best way in which ordinary organisms behave when they 're in groups. example a swarm of ants, a swarm of bees, a colony of microorganism, in these scenario and in many other, biologists have informed us that the workforce of group of individuals itself reveals behavior that the character individuals don 't, or cannot. In other phrases, if we recall the workforce itself as an individual or the swarm in some ways, at least, the whole swarm seems to be more intelligent than any of the members inside it. This remark is the seed for a mass of principles and algorithms, a few of which have become related to swarm intelligence. It turns out that swarm intelligence is handiest closely related to a small element of this mass of principles and algorithms. If we search nature for scenarios wherein a group of agents reveals behavior that the individual doesn’t, it is effortless to find entire and enormous sub-areas of science, certainly in the bio-sciences. Any biological organism seems to exemplify this thought, once we keep in mind the character organism because the 'swarm ', and its cellular add-ons as agents. We could consider brains, and worried programs regularly, as a supreme exemplar of this idea, when person neurons are regarded because the agents or we might zoom in on precise inhomogeneous units of bio-molecules as our 'sellers ', and herald gene transcription, say,

Chapter 2: Literature Review: In this part, several basic concepts are introduced. We start our chapter by explaining the meaning of optimization and its two main categories which are local optimization and global optimization, also the advantages of using the last mentioned category compared to the first one is mentioned. Accordingly, the most know newly invented global optimization algorithms based on nature behaviors like the GA, PSO and GBSA are introduced. In addition of that, the galaxy based search algorithm is studied well and its
The most popular technique in evolutionary computation research has been the genetic algorithm. In the traditional genetic algorithm, the representation used is a fixed-length bit string. Each position in the string is assumed to represent a particular feature of an individual, and the value stored in that position represents how that feature is expressed in the solution. Usually, the string is “evaluated as a collection of structural features of a solution that have little or no interactions”. The analogy may be drawn directly to genes in biological organisms. Each gene represents an entity that is structurally independent of other genes. The main reproduction operator used is bit-string crossover, in which two strings are used as parents and new individuals are formed by swapping a
