Retrosynthetic planning occupies a crucial position in synthetic chemistry and, accordingly, drug discovery, which aims to find synthetic pathways of a target molecule through a sequential decision-making process on a set of feasible reactions.

These assumptions imply that an optimal solutionx?

Next, we also report the average gate activate probability in the normal and reduction cells in Figure 1 (b). At the beginning of the search, we initialize the activation probability of each gate to be one. SameasDARTS, we alternatively update the network parameterW and the architecture parameterβ via gradient descent which is detailed in Algorithm 1. When we compute the gradient βFBtrain(W,β), we ignore the second-order Hessian to accelerate the computation which is the sameasfirst-orderDARTS. For brevity, we usually ignore the notation(k) and i and use X(l) to denote the outputX(l) of any sampleXi ( i = 1,,n) in the l-th layer at any iteration.

NAS family, including DARTS and its variants [11, 12], typically selects many skip connections which dominate over other types of operations in the network graph.
