Rev. 47, 777) in 1935. Here we mentioned the idea of local hidden variable theory(LHVT) and discussed that LHVT is incompatible with quantum mechanics which was claimed by J. S. Bell (Physics 1, 195) in 1964. Here we also discussed the Bell violation by nature.

Here it is shown how to write Hamiltonian can be written and the constraints are optimized to obtain the critical value where the phase transition occurs. As an example graph partitioning problems is taken and the average cost function is calculated which agrees with the numerical values shown by Y. Fu. et. al.

Conventionally, computer system uses mouse as one of the data input devices. But in this system, we use eyes instead of mouse which provides a unique way of operating the computer with the help of eyeball movements.

The formation of clusters were observed based on the opinions. The network topology were monitored even in presence of spamming nodes which eventually forcing an opinion to become dominant in the network. For real-world scenario we have used twitter data for sentiment analysis and to study the formation of opinion clusters.

Then it extended for different batch size of DNA sequences and time analysis were compared between the scratch implementation of the NW algorithm and the built-in method in Biopython package. To overcome the limitation of NW algorithm a sliding
window like scheme was implemented to find the common motif between two DNA sequence of different lengths for different batch size of examples.

The collection of oscillators was studied for couplings varying from weaker to stronger values resulting in the usual phase synchronization within a stipulated time limit. With the variation of some parameters, around some critical values the single synchronized bundle of the constituent oscillators bifurcated into several synchronized coexisting phase bundles. The onset of bifurcation of bundles as a function of initial parameters exhibited some interesting structures.
