Question

an algorithm is the process by which one tests ______ till a best solution is found. every possible solution a series of solutions a couple of solutions

Explanation:

To determine the correct option, we analyze the definition of an algorithm. An algorithm that tests all possible solutions to find the best one is a brute - force algorithm. "Every possible solution" fits this concept. "A series of solutions" and "a couple of solutions" do not imply testing all options, which is characteristic of certain algorithmic approaches to finding the best solution.

Answer:

every possible solution
