Microblogging has taken a considerable upturn in recent years, with the growth of microblogging websites like Twitter people have started to share more of their opinions about various pressing issues on such online social networks. A broader understanding of the domain in question is required to make an informed decision. With this motivation, our study focuses on finding overall sentiments of related topics with reference to a given topic. We propose an architecture that combines sentiment analysis and community detection to get an overall sentiment of related topics. We apply that model on the following topics: shopping, politics, covid19 and electric vehicles to understand emerging trends, issues and its possible marketing, business and political implications.

This paper investigates the induction of Context free Grammar with genetic algorithm. The genetic algorithm is not very effective at this [1]. To overcome this problem we investigate combined effect of two methods for structuring the chromosomes. The first is to bias the distribution of Non-terminals in the chromosome at the time of chromosome generation as well as updating. The latter approach is sequential structural mapping from chromosome to grammar. It is shown that biasing the chromosome in this fashion produces extremely fast convergence as shown in the result section. Grammars are an extremely general and useful tool with many applications. These include the higher levels of signal processing, such as pattern recognition. However, the application of grammars is limited by the algorithms we can apply to infer them from samples of data. The main contribution of this paper is the effective decoding of the context free grammar from chromosomes with the distinct approaches mentioned.

Traveling Tournament Problem is a sports timetabling problem that abstracts the important issues in creating timetables where team travel is an important issue. The instances of this problem seem to be very difficult to solve even for very small cases. In this paper, Author has suggested a Novel encoding scheme for representing a solution instance. The scheme is implemented and tested for several instances of Traveling tournament problem such
