WebTo make it easy to display monetary values, e.g., "$100.00", if a single dollar sign is present in the entire string, it will be displayed verbatim as a dollar sign. This is a small change from regular TeX, where the dollar sign in non-math text would have to be escaped (' $ '). Note WebAnd when the numbers are very large, the epsilon could end up being smaller than the smallest rounding error, so that the comparison always returns “false”. Therefore, it is necessary to see whether the relative error is smaller than epsilon: if ( Math.abs ( (a-b)/b) < 0.00001 ) // still not right! Look out for edge cases
WebMar 24, 2024 · Epsilon () parameter is related to the epsilon-greedy action selection procedure in the Q-learning algorithm. In the action selection step, we select the specific action based on the Q-values we already have. The epsilon parameter introduces randomness into the algorithm, forcing us to try different actions.
