Use Dynamic programming technique to solve the setpartition problem.
See the problem definition below.
Define the object function, write the recursive relation, give the initial condition, illustrate the table,
indicate where the answer is and estimate the time complexity and space complexity.
Is the algorithm in part a polynomial time algorithm? Explain.
Setpartition problem:
Given a set of positive integers, dots,
is there a partition of into two disjoint subsets A and A such that
Give a Huffiman binary coding tree for the following data: ABCATDABEBAAAAAABEB.
Compute the total number of bits to send this message.
Give a Huffiman ternary coding tree for the data in part
Describe the BellmanFord algorithm for solving the shortest path problem.
State the time complexity. Is it a polynomial time algorithm?
Consider the graphs containing negative weight cycles. Can BellmanFord algorithm find a
shortest path between two nodes? Explain or prove.
Is there a polynomial time algorithm to find a negative weight cycle? Explain or prove.
Is there a polynomial time algorithm to find the largest negative weight cycle? Explain or prove.
A negative weight cycle such that the absolute value of its total weight is maximum..When we implement a binary search tree, we need to define a class or a
struct for node. In a node, we have three fields, one for data, and two
pointers leftChild and rightChild. If we have a binary search tree of
nodes, show that there must be unused pointer fields, regardless
the tree looks like.
