Give pseudocode that performs the traceback to construct an LCS from a filled dynamic programming table without using the “arrows”, in O(n + m) time. 2. Suppose we are given a “chain” of n nodes as shown below. Each node i is “neighbors” with the node to its left and the node to its right (if they exist). An independent set of these nodes is a subset of the nodes such that no two of the chosen nodes are neighbors....

Instructions Write a program in Java that implements the A* algorithm to find a path from any two given nodes. Problem Overview & Algorithm Description In a fully-observable environment where there are both pathable and blocked nodes, an agent must find a good path from their starting node to the goal node. The agent must use the A* algorithm to determine its path. For this program, you must use the Manhattan method for calculating the heuristic. Remember: your heuristic function...

3. Give an efficient algorithm that takes as input a directed graph G-(V,E) with edges labeled with either 0 or 1, and vertices s and t that ouputs TRUE if and only if there is a path (not necessarily simple) that goes from s to t such that the binary sequence of edges in the path avoids the substring "11" and outputs FALSE otherwise. (For example, the string 10100010 avoids 11 but the string 00101101110 does...
