Question

Describe the appropriate load factors for the following collision handling strategies from experimental perspective? (2 points)

(a) linear probing
(b) quadratic probing
(c) separate chaining
(d) double hashing

Answer 1

The appropriate load factors for collision handling strategies are determined experimentally. Linear probing, quadratic probing, separate chaining, and double hashing each have different load factor recommendations to avoid clustering and performance degradation.

Step-by-step explanation:

The appropriate load factors for collision handling strategies can be determined experimentally. Let's discuss them for each strategy:

1. Linear probing: In linear probing, the load factor should preferably be kept below 0.5 to avoid excessive clustering and performance degradation.
2. Quadratic probing: For quadratic probing, the load factor should typically be limited to around 0.7 to maintain good performance and minimize clustering.
3. Separate chaining: In separate chaining, the load factor can be higher without causing clustering issues. It is often recommended to keep the load factor below 0.9 for this strategy.
4. Double hashing: Similar to linear probing, double hashing is also prone to excessive clustering as the load factor increases. It is advisable to keep the load factor below 0.5.
