Boris the chest master selects his next move by considering moves that would threaten his opponent's queen. his opponent, a chess-playing computer, selects its next move by considering all possible moves. boris is using a(n) and the computer is using a(n)

Heuristic and Algorithm  

Explanation:

Algorithm: It is processed to solve the process step by step. It is a finite source if followed step by step will solve the problem correctly. Computer and programming are other tools that are used to solve the problems. The algorithm is the correct, efficient and easy to implement for the solution of a problem.  

A heuristic is another technique to solve the problem. But it does not work on finding the solution but it works how the problem looks. It is a technique to look for the answer.

heuristic; algorithm                                          

Explanation:

Heuristic: This is referred to as an approach to learning, discovery, or problem-solving, that implements a practical method which is not insured to be perfect or optimal, yet sufficient enough to fulfill the ultimate and immediate goals.

Algorithm: This is one of the methods that use a step-by-step method to solve a specific problem. The algorithm method is commonly used for calculation, data processing and other mathematical and computer operations. It is also used for manipulating data in various ways.

In the question above, Boris is using a heuristic and the computer is using an algorithm.

the correct answer is "hematoma formation, with ligaments that are stretched, partially, of fully torn" ankle sprain are produced by an injury to the tough bands of tissue (ligaments) that surround and connect the bones of the leg to the foot. this causes several damage to the ankle including hematoma formation and ligament injury .

probably 3 since archeologists and historians don’t understand there writing.
