// --------------------------------------------------
// --------- SPECIAL CONFIGURATION OPTIONS ----------
// --------------------------------------------------
 
// Use single parameter points instead of parameter intervals.
// Comment this setting out for the final computations.
//#define CONFIG_PARAMPOINTS
 
// Do not send individual parameter boxes for precomputing
// the Conley indices.
#define CONFIG_NOPREPROCESSING
 
// Use the procedure for computing the Morse decomposition
// instead of computing the invariant part of the set,
// and also don't determine connections between Morse sets.
// In this way, the connections between Morse sets are lost,
// but the invariant part to subdivide may be substantially smaller.
// Comment this setting out for the final computations
// to get full information.
//#define CONFIG_NOCONNECTIONS
 
// Use the default bounding box for ODE integration in order to prevent
// iterating trajectories far beyond the phase space of interest,
// and, in particular, to avoid running out of the scope of integer
// coordinates of boxes when determining the images of boxes.
// WARNING: This technique may lead to the construction of combinatorial
// cubical multivalued maps that are not acyclic, that is, do not satisfy
// the necessary assupmtions for the computation of the homomorphism
// induced in homology (for the Conley index map).
// NOTE: If using the approximate integration of the ODE, this technique
// works in a different way, by fading the vector field outside the box,
// so it is safe to use it in that setting.
