Heuristic System

The term heuristic is derived from the Greek word heurisko, which means “I find, discover”. Heuristics can be mental shortcuts or approaches designed from previous experiences. The main aim of the heuristic approach is to find a good enough solution to solve the problem. Test and mistake, rule of thumb, or an educated estimate are all examples of heuristics. These methods are sufficient for achieving an immediate, brief aim. When a heuristic is used in practice, it works as predicted. It can, however, produce systematic errors. Trial and error is an important heuristic that may be used in a variety of situations, from cross-linking nuts and bolts to determining the values of given input variables in mathematical puzzles. Additional hypotheses, visual illustrations, simplification, and forward or backward reasoning are all common heuristics in mathematics.

Consider the magic triangle of 6 numbers, in which the numbers from 1 to 6 must be placed in the six positions indicated in the following figure, in such a way that all the sides of the triangle add up to 10. In order to solve the magic triangle problem, we want to use uninformed search algorithms. To do this, it is considered that it starts with an empty triangle, and the six numbers are placed one by one, starting with 1, until all 6 spaces are filled. That is, selecting the space for number 1 proceeds to select the space for number 2 among the remaining five circles, and so on. If when you finish placing the 6 numbers you have a triangle where its three sides add up to 10, you have a valid solution. You need to describe the problem and create a search tree with at least 4 levels: width search and depth search. What is the path to the solution so far in each tree and which algorith solves is best?

True or False In a weighted graph, edges have an associated number called weight, which might represent distances, costs, times, or other quantities. The minimum spanning tree in a weighted graph minimizes the total weights of the edges necessary to connect all the vertices. Graphs can represent many real-world entities, including airline routes, electrical circuits, and job scheduling. The adjacency matrix can be used to represent a graph's edges in a computer program. Topological sorting is useful for scheduling projects which contain many tasks contingent on other tasks. There may be many correct topological sorts for a given graph. You can create a topological sort of a graph that contains cycles.
