The minimum edge count (MEC) and optimal Jacobian accumulation problems in linearized directed acyclic graphs (DAGs) result from the combinatorics induced by the associativity of the chain rule of differential calculus. This paper discusses a suitable graph formalism followed by proving a number of results that yield a considerable search space reduction for both problems. An algorithmic link between numerical analysis and theoretical computer science is established. Although both problems are believed to be NP-hard in general, a linear-time algorithm is presented solving theMECproblem for a specified subclass of l-DAGs.
