About Transcript The squeeze (or sandwich) theorem states that if f (x)≤g (x)≤h (x) for all numbers, and at some point x=k we have f (k)=h (k), then g (k) must also be equal to them. We can use the theorem to find tricky limits like sin (x)/x at x=0, by "squeezing" sin (x)/x between two nicer functions and using them to find the limit at x=0.A graph Gs=(V,Es) is a sandwich for a pair of graphs Gt=(V,Et) and G=(V,E) if Et⊆Es⊆E. A sandwich problem asks for the existence of a sandwich graph having an expected property.Let G S (V,E S ) be a sandwich graph of graphs G 1 (V,E 1 ), G 2 (V,E 2 ). The edges in E 1 are called mandatory edges, once each and every sandwich graph of (G 1 ,G 2 ) has to contain them. On the other hand, the edges not in E 2 are said to be forbidden edges, meaning that no sandwich graph of (G 1 ,G 2 ) is al- lowed to contain them.J Braz Comput Soc (2012) 18:85–93 DOI 10.1007/s13173-012-0065-7 SI: GRAPHCLIQUES Sandwich problems on orientations Olivier Durand de Gevigney ·Sulamita Klein · Viet-Hang Nguyen ·Zoltán Szigeti Received: 1 February 2012 / Accepted: 3 February 2012If such a graph exists, then it is called sandwich graph.
