Use a tree to test whether the following wff is satisfiable. If it is, then read off from your tree a model on which it is true. ∃x∃y∀z(¬(¬x = y ∨ ¬Ryxy) ∧ ¬Rxyz)

For the following use the method of "primitive counting" described in class:   Turn the following strings of 1s and 0s into the appropriate number of sheep, drawing the ternary tree is desired:   1,0,1,0,1,0 1,0,1,0,1,0,1 1,0,1,1,0,0,0,

Consider the following trees for the sentence : I shot an elephant in my pajamas (a) S NP Precision: VP Recall: NP F-1 score: NP PP NP (b) S NP VP NP Pro V Det Noun P Poss Noun Pro V Det Noun P Poss Noun | | I shot an elephant in my pajamas I shot an elephant in my pajamas PP Where tree (a) is the Gold-standard tree and tree (b) is the tree generated by our system. We our evaluating our tree against the gold-standard. Calculate the following (Denote your answers in following format: num/denom) NP

Given a binary search tree and data of two nodes, find 'LCA' (Lowest Common Ancestor) of the given two nodes in the BST.LCALCA of two nodes A and B is the lowest or deepest node which has both A and B as its descendants. Example:In this example, the green coloured node is the LCA to A and B.Alt TextNote:It is defined that each node is a descendant to itself, so, if there are two nodes X and Y and X has a direct connection from Y, then Y is the lowest common ancestor.Example:Alt TextNote:1. If out of 2 nodes only one node is present, return that node. 2. If both are not present, return -1.3. all the node data will be unique.Input format:The first line of input contains data of the nodes of the tree in level order form. The data of the nodes of the tree is separated by space. If any node does not have left or right child, take -1 in its place. Since -1 is used as an indication whether the left or right nodes exist, therefore, it will not be a part of the data of any node.The following…

Test the validity of the following argument, using the tree method: premise (a) Every Greek who loathes a Trojan is feared by all. premise (b) Achilles loathes a Trojan. Conclusion (c) If Achilles is Greek, everyone fears him. Formal Logic.
