Error tolerance refers to the acceptable level of error in numerical computations and approximations, particularly when using iterative methods to find solutions. In the context of optimization algorithms, such as Newton's method, it determines how close an approximate solution needs to be to the exact solution before the algorithm can be considered successful. This concept is crucial in ensuring that calculations remain feasible and efficient without sacrificing accuracy significantly.
congrats on reading the definition of Error Tolerance. now let's actually learn it.
