Many of the symbolic methods prevalent in dynamical modeling were
designed specifically for a certain class of "nice" models, such as,
e.g., polynomials with integer coefficients. However, in practice many
models contain components that are not easily accessible to purely
symbolic manipulations, such as floating point coefficients and
exponents, lookup tables, or piecewise defined functions. The challenge
is to apply symbolic techniques to such models appropriately and
effectively.
In this presentation we would like to list some of the problems that are
often encountered when dealing with real world applications. We then
present some possible solutions applicable in some cases. Most
importantly, we would like to initiate a discussion with the audience on
how to approach these issues.
