// --------------------------------------------------
// --------- 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
 
// Do preprocessing only and skip the matching part.
//#define CONFIG_ONLYPREPROCESSING
 
// Wait with Phase 2 until Phase 1 (preprocessing) has been completed.
#define CONFIG_SEPARATEPHASES
 
// 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.
//#define CONFIG_ODEBOUNDINGBOX
 
// Make a correction to the isolating neiborhood after subdivision.
// This is necessary for integrating ODEs using the time-t map
// with variable t, because an isolating neighborhood for one t
// need not be an isolating neighborhood for another t, so it is only taken
// as a hint, and those cubes from the exit set whose images intersect
// the isolating neighborhood are added to the isolating neighborhood,
// like in an algorithm for the construction of an index pair.
//#define CONFIG_ODEVART
 
// Add cubes to the image of a combinatorial cubical multivalued map
// only if their intersection with the interval box that covers the image
// is equal or higher to the provided fraction.
// Set the fraction to 0 to add whenever they intersect (old behavior),
// set the fraction to a maximum of 1 (to add those only which are contained).
//#define CONFIG_IFRACTION 0.05
 
// Enhance the invariant part the given number of times
// before proceeding to the next subdivision level.
//#define CONFIG_ENHANCEINV 1
 
// Define the X coordinate for plotting the Morse sets in the PNG files.
//#define PLOT_X_COORD 1
 
// Define the Y coordinate for plotting the Morse sets in the PNG files.
//#define PLOT_Y_COORD 3
