fibonacci heaps
Fibonacci heaps are a data structure containing a collection of items with key values. They are characterized by their ability to optimize certain operations, such as inserting, merging, and decreasing key, in amortized constant time. The structure consists of a collection of trees that satisfy the Fibonacci heap properties. These properties include the minimum-heap property, which ensures that the key of each node is greater than or equal to the key of its parent, and the Fibonacci property, which restricts the degree (number of children) of any node. The presence of multiple trees with different degrees allows the Fibonacci heap to efficiently perform various operations.
