Program Plan Intro

Best-first-search algorithm:

The best-first-search algorithm is a search algorithm used to search a particular node of a graph.

This search algorithm explores the graph like, it chooses a most promising node according to some specific rules.

The best-first-search algorithm refer specifically to a search with a heuristic. This search tries to predict how close the end of a path is to a solution, so that paths that are considered closer to a solution are extended first.

The specific type of search is called pure heuristic search or greedy best-first search.

**A* search algorithm:**

The A* search algorithm is a search algorithm used to search a particular node of a graph.

A* algorithm is a variant of the best-first algorithm based on the use of heuristic methods to achieve optimality and completeness.

The algorithm A* is an example of a best-first search algorithm.

If a search algorithm has the property of optimality, it means that the best possible solution is guaranteed to be found. Here, the user wants the shortest path to the final state.

Uniform cost search:

The uniform cost search algorithm is used to traverse weighted tree or graph.

The ultimate aim of the uniform cost search is that to find the goal node that has the lowest cumulative cost.

The uniform cost search expands nodes based on the root node’s path cost.

The algorithm is used to solve the graph, tree where the cost is in demand.

Consider the following expression in C: a/b > 0 && b/a > 0. What will be the result of evaluating this expression when a is zero? What will be the result when b is zero? Would it make sense to try to design a language in which this expression is guaranteed to evaluate to false when either a or b (but not both) is zero? Explain your answer.

Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid."
