Salesman Problem Essay
The Travelling Salesman Problem (TSP) is well known in the field of combinatorial optimization. It is a NP-complete problem and there is no efficient method to solve this problem and give best result. Many algorithms are used to solve travelling salesman problem. Some algorithms give optimal solution but some other algorithms gives nearest optimal solution. The genetic algorithm is a heuristic method which is used to improve the solution space for genetic algorithm. The genetic algorithm results in nearest optimal solution within a reasonable time. This paper mainly focuses on various stages of genetic algorithm and comparative study on various methods used for genetic algorithm. The paper also proposes a method to solve the travelling salesman problem and hence improve the solution space.

I. INTRODUCTION
Optimization is the process of making something better. An optimization problem is the problem of finding the best solution from all available solution spaces. The terminology “best” solution implies that there is more than one solution. Travelling salesman problem also results in more than one solution but the aim is to find the best solution in a reduced time and the performance is also increased. So the heuristic genetic algorithm is used.

591 Words | 3 PagesTo get started the LAN would be the main configuration for connecting the computers on each floor with star typology. Star topology will connect all nodes individually to a central connection point also known as the switch. A pro with this configuration if a cable fails only one node will be brought down and the rest will continue running. In addition, we can use twisted pair for the wire used to simply to cancel out electromagnetic interface from external sources since there will be multiple computers next to each other. The copper wire will lead to a switch connecting the devices together on the same network.

598 Words | 3 PagesUnderstanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
