Hello, Would anyone be able to help me find an algebraic equation sequencer (like Knuth's topological processor) that will order a system of equations for nonlinear optimization similar to GAMS/AMPL? eg A[t]=A[t-1]+B[t] with perhaps sum(A) to be optimised by changing B[t] and other constraints. I imagine that something could be done with mathgraph. Thanks, Stuart -- DISCLAIMER: This email message and any accompanying atta...{{dropped:10}}
