We generalize the Caristi’s fixed point theorem for single valued as well as multivalued mappings defined on a metric space endowed with a graph and w-distance. Particularly, we modify the concept of ...

Key points about graphs of inequalities Show values that satisfy an inequality on a set of axes by drawing the line of the corresponding equation and shading the area specified in a question.

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

The 'line of best fit' is a line that goes roughly through the middle of all the scatter points on a graph. The closer the points are to the line of best fit the stronger the correlation is. This ...
