WebThe Web Graph is a large-scale graph that does not fit in main memory, so that lossless compression methods have been proposed for it. This paper introduces a compression scheme that combines efficient storage with fast retrieval for the information in a node. The scheme exploits the properties of the Web Graph without assuming an ordering of the … WebVertical Stretches and Compressions. When we multiply a function by a positive constant, we get a function whose graph is stretched vertically away from or compressed vertically toward the x-axis in relation to the graph of the original function. If the constant is greater than 1, we get a vertical stretch; if the constant is between 0 and 1 ...

GraphZIP: a clique-based sparse graph compression method

WebHow To: Given a function, graph its vertical stretch. Identify the value of a a. Multiply all range values by a a. If a > 1 a > 1, the graph is stretched by a factor of a a. If 0 < a< 1 0 < a < 1, the graph is compressed by a factor of a a. If a < 0 a < 0, the graph is either stretched or compressed and also reflected about the x x -axis.
