Restrictions on Problem Size.

There are size restrictions in the file auto/07p/include/auto.h on the following AUTO-constants : the effective number of equation parameters NPAR, and the number of stored branch points NBIF for algebraic problems, See Chapter 10 for the significance these constants. Their maxima are denoted by the corresponding constant followed by anX. For example, NPARX in auto.h denotes the maximum value of NPAR. If any of these maxima is exceeded in an AUTO-run then a message will be printed. The exception is the the maximum value of NPAR, which, if exceeded, may lead to unreported errors. Upon installation NPARX=36; it should never be decreased below that value; see also Section 11.1. Size restrictions can be changed by editing auto.h. This must be followed by recompilation by typing make in directory auto/07p/src.

Note that in certain cases the effective dimension may be greater than the user dimension. For example, for the continuation of folds, the effective dimension is 2NDIM+1 for algebraic equations, and 2NDIM for ordinary differential equations, respectively. Similarly, for the continuation of Hopf bifurcations, the effective dimension is 3NDIM+2.
