One of the most fundamental principles in our world is the search for an optimal state. Many real life applications in operations research and computer science are formulated as optimization problem.These real life problems are non-linear in nature having the characteristics like multi-mode, non-continuous etc. So, it is very difficult to solve these problems by tools like gradient descent, Secant method etc. Here comes the concept of global optimization.\\
Global optimization is a branch of applied mathematics and numerical analysis that deals with the global optimization of a function or a set of functions according to some criteria.
Global optimization is distinguished from regular optimization by its focus on finding the maximum or minimum

Then we can efficiently explore our search space. If there is no relationship observed or the dimentionability of search space is high then it become very hard to solve any problem deterministically. Then we have to do large number of enumerations even for a very small problem. Then comes the role of probabilistic algorithms.\\ \item \textbf{Probabilistic Algorithms:} These are generally referred as Monte-Carlo algorithms which provides a good solution in shorter time. They doesn't provide exact solution of a problem but a good solution near to optima which would have taken years by deterministic algorithms.\\\\

It is a part of optimization algorithm which uses the information gathered by the algorithm to decide which solution candidate to be tested next or how to reach the next solution candidate.It is a local search. Heuristic are problem dependent. Heuristics can be used by both deterministic and probabilistic algorithms.
\item \textbf{Meta-heuristics:} It is a Heuristic method for solving general class of problem. It is generalized local search. Meta-heuristic are problem independent that can be applied to wide range of problems. Generally all the probabilistic algorithms uses Meta-heuristics. \end{enumerate} The algorithm that we are trying to implement is a probabilistic algorithm. In our algorithm either we are randomly picking points from domain of function or applying gradient descent method with probability p and 1-p respectively. There are four different versions of algorithms that we have implemented. The algorithm is tested by simulations performed on benchmark function in MATLAB.

Strategies are methods or plans that solves a problem; strategies are essential to resolve issues to be able to prevent them from happening again and it helps to do a better job. Computerized physician’s order, electronic medication administration record with a barcode and reviewing the practice standards from CNO such as medication and documentation are the suggested strategies to inhibit the incidents and the breached ethical values from occurring again. Moreover, using information technology is the first strategy to impede medication error in the long-term care facility where an ethical value such as commitment to client was breached.

Companies like FedEx use them to determine the effects of price change or new services, and has seen 65%-90% accuracy. This ability to determine the best solution before it happens is an incredible achievement. Making changes that aren’t well receptive can cost your business customers, reputation, and much more. Putting out the right plan the first time can save your face and more importantly, you cash flow. For the city planner, predicting which bus stops will have the

Globalization is a process of interaction and integration among the people, companies, and governments of different nations, a process driven by international trade and investment and aided by information technology. This process has effects on the environment, on culture, on political systems, on economic development and prosperity, and on human physical well-being in societies around the world. The most common example of globalization might be Ebay or Amazon. Nowadays flows of goods and services are not only cheap and fast, but reliable and secure.
To understand the full theory and its impact, the main ideas, the importance, the research done with it, and its strengths and weaknesses must be
Globalization means that people from. different countries communicate together and work together. The world is becoming globalizing because many people have benefits in globalization. Business men can set up their business in other countries. Also ,we can have better communication with other countries’ people through the widely used language, like English.
