سوال ۲۷ کنکور ارشد علوم کامپیوتر ۱۳۹۸

Read the following excerpt from PASSAGE 3 and complete the sentence by choosing the option that fits the meaning of the passage.

Solving an IEP can generally be regarded as solving a nonlinear algebraic system. It is not surprising that many existing computational techniques can be applied to solve an IEP. ... We have found from the literature that current numerical procedures for solving IEPs can roughly be classified into three categories. These are: 1. direct approach, 2. iterative approach, 3. continuous approach. ... Direct approach. By a direct method, we mean a procedure through which a solution to an IEP can be found in finitely many arithmetic operations.

There are many computational techniques for solving nonlinear algebraic systems, _______ approach exists for solving certain IEPs.
