... single node, which is the maximum number of children it can have. In a regular Binary tree b=2. In a B+ tree b can be any number, but for convenience it is preferred to use multiples of 2. B+ Tree is an external tree, which means that traversal (or internal) nodes contain only keys and pointer/refer ...

... 3. (10 pts) It is known that Dijkstra’s algorithm does not work for graphs with negative edges. Consider the following modification to Dijkstra’s algorithm for `solving’ the shortest path problem for graphs with negative edges but without negative cycles. If some of the edge weights in a graph are ...

... class non-deterministic. If you twice insert the same values into a skip list, you may end up with very different internal links. Random chance used in the right way can be a very powerful tool. In one experiment to test the execution time of the skip list we compared the insertion time to that of a ...

Checking Data Structure Properties Orders of Magnitude Faster
... Intuitively, we memoize whatever the program’s formal contracts need, and use the data structure itself as the storage space. A function is eligible to be memoized, if 1) it is called (directly or indirectly) from a formal contract (otherwise its value is not needed for runtime checks), 2) it has a ...
