Bisection for sga solving onemax and trap-5

WebJun 24, 2024 · The bisection method bases all decisions purely on the sign of the function value. There is no size information used, even less slope information. Thus even if the root were $3.500001$ so that the best approximation could be found in the first step, there is no way to detect this, the result of the first step is only that the root is somewhere ...
