Binary neutron stars are among the most promising candidates for jointgravitational-wave and electromagnetic astronomy. The goal of this work is toinvestigate the strategy of using gravitational wave sky-localizations forbinary neutron star systems, to search for electromagnetic counterparts usingwide field of view optical telescopes. We examine various strategies ofscanning the gravitational wave sky-localizations on the mock 2015-16gravitational-wave events. We propose an optimal tiling-strategy that wouldensure the most economical coverage of the gravitational wave sky-localization,while keeping in mind the realistic constrains of transient optical astronomy.Our analysis reveals that the proposed tiling strategy improves thesky-localization coverage over naive contour-covering method. The improvementis more significant for observations conducted using larger field of viewtelescopes, or for observations conducted over smaller confidence interval ofgravitational wave sky-localization probability distribution. Next, weinvestigate the performance of the tiling strategy for telescope arrays andcompare their performance against monolithic giant field of view telescopes. Weobserved that distributing the field of view of the telescopes into arrays ofmultiple telescopes significantly improves the coverage efficiency by as muchas 50% over a single large FOV telescope in 2016 localizations while scanningaround 100 sq. degrees. Finally, we studied the ability of optical counterpartdetection by various types of telescopes. In Our analysis for a range of widefield-of-view telescopes we found improvement in detection upon sacrificingcoverage of localization in order to achieve greater observation depth for verylarge field-of-view - small aperture telescopes, especially if the intrinsicbrightness of the optical counterparts are weak.
