How Can I Efficiently Implement a Priority Queue in .NET Using C5?

Leveraging C5 for High-Performance Priority Queues in .NET

Standard sorting algorithms aren't ideal for dynamic data insertion; priority queues offer a superior solution. Unlike resorting the entire dataset with each addition, priority queues provide efficient insertion and retrieval of elements based on their priority.

Core Priority Queue Operations:

• Insert(Q, x): Inserts element 'x' with its associated key 'k' into queue 'Q'.
• Find-Minimum(Q): Retrieves the element with the lowest key value.
• Delete-Minimum(Q): Removes and returns the element with the lowest key value.

C5: The .NET Solution

The .NET framework lacks a built-in priority queue implementation. However, the C5 Generic Collection Library provides a robust and efficient solution: the IntervalHeap.

IntervalHeap Advantages:

• Employs an interval heap data structure, represented as an array of key-value pairs.
• FindMin and related minimum operations, along with indexer access, boast O(1) time complexity.
• Operations such as Add, Update, DeleteMin, and indexer assignment maintain a commendable O(log n) time complexity.

Practical Application:

<code class="language-csharp">var heap = new C5.IntervalHeap<int>();
heap.Add(10);
heap.Add(5);
heap.FindMin(); // Returns 5</code>
