![]() Although this is nearly the same problem on the complement graph, for specific families of graphs this is a more natural way of viewing it. In this thesis, we study a natural variant of this problem which is to consider graphs where vertices represent distinct sets and adjacencyĬoincides with disjointness. In that paper it was shown that the problem is NP complete. and they looked at minimising the underlying universal set necessary to represent any given graph. Of representing a graph as an intersection graph of sets was first introduced by Erdos et al. The sets are usually required to conform to some template, depending on the problem, to be either a finite set, or some geometric set like intervals, circles, discs, cubes etc. One can also study the reverse problem of expressing the vertices of a given graph as distinct sets in such a way that adjacency coincides with intersection of the corresponding sets. Sometimes these sets are finite, but in many well known examples like geometric graphs (including The screenshot will be saved to your desktop.Given a set of nonempty subsets of some universal set, their intersection graph is defined as the graph with one vertex for each set and two vertices are adjacent precisely when their representing sets have non-empty intersection.When you release the mouse, the picture will snap.Drag the crosshair icon to enclose the section of the screen you want to snap.To capture a partial screen still shot from a video with hotkeys on a Mac: To capture a full-screen still shot from a video with hotkeys on a Mac, press Shift, Command, and 3. If you are using an older version of Windows, the screenshot will be copied to your clipboard from there, you can paste it into a document or Paint and save it. On Windows 8 or 10, the shot will be saved to the Screenshots folder in your Pictures Library. To capture a still shot from a video with hotkeys on Windows, press Win and Print Screen simultaneously or, on some laptops, press Function and Print Screen. Automatically captures the entire screen – no option to capture a specific portion.You have to remember the key combination.You might also want to consider downloading the Movavi ScreenShot, a Google Chrome extension that captures high-quality screenshots in your browser.Īnother way to capture a screenshot from a video is to use hotkeys, which are shortcuts you can take by pressing a succession of keys or a few keys at once.
