WebbThe idea of the linear step is to perform a quick search in the direction that is likely to be a descent direction. The pseudocode of the linear step in the DQL method is shown in Algorithm 4. Note that in order to perform Line 2 of Algorithm 4, there are two components we need to determine: the desired direction and the step length(s).
