Your experimental results for exercise sheet 1
Please sumarize your results from exercise sheet 1 in a row in the table below. In the first column, write your name (abbreviate if you are in a group, to keep it short). In the second column, put the programming language you used (C++ or Java). In the third column put the average running time (in seconds) for 1000 random queries using Dijkstra's algorithm. In the fourth column put the average running time (in seconds) for 1000 random queries using A-star with the straightline heuristic. In the last column put the name of the dataset you computed these average times on (preferably Ba-Wü, but if that didn't work Saarland).
Here is the table with the correspondence Road Types <-> Speeds.
Note(Hannah): Saarland has about 400K non-isolated nodes, Ba-Wü has about 5M non-isolated nodes. (K stands for thousand, M stands for million, also in the table below.)
Note(Hannah): There are quite a number of road types not considered in our table. These account for more than half of the arcs in the two networks. If I take them into account (with a speed of 5 km/h, but that doesn't really matter) by average query times and the number of settled nodes more than doubles.
