Route Optimization API - Patherizer (a solution to vehicle routing problem) is a cross browsers REST API supporting now a maximum of 100 stops per route or request including the start destination and the end destination. Beeing a multi stop route optimization software, Patherizer may be used by multiple calls to calculate and optimize routes for multiple vehicles, each vehicle with its optimized route. The route optimization API algorythm is based per TSP (travel salesman problem) and it always calculate the shortest route betwween current stop and the next stop until it reaches the end destination. The input addresses are geocoded, so the JSON response will include latitude and longitude of each stop. If the route optimization API cannot recognize one or more of the input addresses it will not geocode these inputs and the API request will return a JSON Error as specified in the errors table. The Route Optimization API JSON response also includes distances between each stops along the optimized route (in miles or km) and most important, the durration (in seconds) and durration in real traffic conditions (in seconds) at the time you make the request. A total distance of the optimized route is computed and also a total time.
