An embodiment of the invention provides an extremum route determining engine and method. The engine includes a memory for storing a path with a weight in a graph and an extremum route determining logic circuit. The logic circuit includes a path reading section for reading the path in the graph, a writing section for updating the weight of the read path according to a predetermined extremum requirement and writing the path whose weight is updated into the memory, and an extremum route determining section for determining an extremum route. The method includes reading a stored path in a graph, the path having a weight, updating the weight of the read path and writing the path whose weight has been updated into a memory, and determining an extremum route. An embodiment of the invention improves the processing speed of extremum route determination.
