... tractability and the quality of the lexicalization. The Problem of the Lexiealization of a Grammar Given a lexicalized grammar, this part describes the problem of the optimization of the computational ... in the input. The first step of the optimization of the lexicalization is to assign a weight to each rule. The weight is assumed to represent th...

... f ij > 0 then we interpret that the node j activates the node i by increasing the net rate of x i and if f ij < 0 then the node j inhibits the node i. We note that the dynamics of the system ... interaction’) for the unknown sign of f ij . We can then obtain the feasible network signs (FNS) at x i by excluding the INS from the all network signs (ANS) as a c...
