Although simple route planning is not as daunting as TSP, there are some similarities, in that it involves a weighted, undirected graph, requiring the algorithm to take into account the cost of ...

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 ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in ...

Solve quadratic equations by factorising, using formulae and completing the square. Each method also provides information about the corresponding quadratic graph.
