Variable Documentation

◆ compareMorseOrdering

const bool custom::whales::compareMorseOrdering = true

Should the ordering between the Morse sets be taken into consideration while determining whether two Morse decompositions computed for adjacent parameter boxes are in the same class?

Definition at line 188 of file p_whales.h.

◆ finalDepth

const int custom::whales::finalDepth = 11

The final depth of subdivisions in the phase space.

Definition at line 59 of file p_whales.h.

◆ ignoreIsolationForConleyIndex

const bool custom::whales::ignoreIsolationForConleyIndex = false

Ignoring the isolation problem while computing the Conley index.

If the constant is set to "true" then the index pair constructed on the basis of a combinatorial Morse set with respect to the dynamics restricted to the rectangular area of interest is also restricted to that area by means of projecting all the boxes that stick out of the region onto a single layer of boxes around the boundary.

Definition at line 203 of file p_whales.h.

◆ ignoreIsolationForContinuation

const bool custom::whales::ignoreIsolationForContinuation = true

Ignoring the isolation problem while matching Morse decompositions.

If this constant is set to "true" then Morse sets are matched with each other indepent of whether the Conley index could be computed for them or not. Otherwise, 'correct' and 'wrong' Morse sets are matched with their counterparts in the same category only.

Definition at line 195 of file p_whales.h.

◆ initialDepth

const int custom::whales::initialDepth = 6

The initial depth of subdivisions in the phase space.

Definition at line 56 of file p_whales.h.

◆ maxImageDiameter

const int custom::whales::maxImageDiameter = 10000

The maximal allowed diameter of the cubical image of a signle box.

This limit is set up in order to prevent a blow-up of the program in the memory because of accumulating huge images of boxes.

Definition at line 146 of file p_whales.h.

◆ maxImageVolume

const int custom::whales::maxImageVolume = 100000

The maximal allowed volume of the cubical image of a single box.

This limit is set up in order to prevent a blow-up of the program in the memory because of accumulating huge images of boxes.

Definition at line 151 of file p_whales.h.

◆ maxIndexPairSize

const int custom::whales::maxIndexPairSize = 10000000

The maximal allowed size of the index pair.

This size is measured as the total number of cubes in the index pair and its forward image.

Definition at line 160 of file p_whales.h.

◆ maxJoinConnection

const int custom::whales::maxJoinConnection = 1000

The maximal size of a connecting orbit between two Morse sets which can be considered for joining.

Definition at line 174 of file p_whales.h.

◆ maxJoinDistance

const int custom::whales::maxJoinDistance = 100

The maximal allowed distance between two Morse sets which can be considered for joining.

Note: It doesn't work with space wrapping.

Definition at line 178 of file p_whales.h.

◆ maxJoinSize

const int custom::whales::maxJoinSize = 0

The maximal number of cubes in a trivial Morse set for which an attempt is made to join this set with another near-by Morse set.

Set to zero to suppress joining.

Definition at line 170 of file p_whales.h.

◆ maxRefineSize0

const int custom::whales::maxRefineSize0 = 10000

The maximal allowed size of a set of cubes in the phase space which can be refined at the initial subdivision level.

Set to zero to suppress any refinements.

Definition at line 131 of file p_whales.h.

◆ maxRefineSize1

const int custom::whales::maxRefineSize1 = 5000

The maximal allowed size of a set of cubes in the phase space which can be refined at the subsequent subdivision levels.

Set to zero to suppress any refinements.

Definition at line 136 of file p_whales.h.

◆ paramCount

const int custom::whales::paramCount = 5

The number of all the parameters, both varying and fixed.

0 - survival rate for adults: s_a in [0,1] 1 - survival rate for juveniles: s_j in [0,1] 2 - alpha = e^r > 1 (e.g. e^{4} = approx 54.598) 3 - beta > 0 (e.g. e^{r-1} = 20.086 - phase space scaling factor) 4 - options bits: 0x010 for "s_j := 1 - s_a", 0x020 for "s_j := s_a", 0x100 for "beta := alpha / e".

Definition at line 91 of file p_whales.h.

◆ paramDim

const int custom::whales::paramDim = 2

The dimension of the parameter space to iterate.

Only those parameters which are varying are taken into consideration here.

Definition at line 68 of file p_whales.h.

◆ paramLeft

const double custom::whales::paramLeft[paramCount]
Initial value:
= {0.0, 0.0,
54.598150033144236, 20.085536923187668, 0x100}

The left bounds on the parameters.

Definition at line 94 of file p_whales.h.

◆ paramRight

const double custom::whales::paramRight[paramCount]
Initial value:
= {0.9, 0.9,
54.598150033144236, 20.085536923187668, 0x100}

◆ paramSelect

const int custom::whales::paramSelect[paramDim] = {0, 1}

Definition at line 75 of file p_whales.h.

◆ paramSubdiv

const short int custom::whales::paramSubdiv[paramDim] = {100, 100}

The numbers of subintervals in each direction of the parameter space.

The type of these numbers must match "parCoord" in "typedefs.h".

Definition at line 72 of file p_whales.h.

◆ refineDepth

const int custom::whales::refineDepth = 15

The number of refinements that should be done if a Morse set with the trivial index is encountered or if the image of a Morse set sticks out of the rectangular region to which the computations are restricted.

Set to zero for no refinements.

Definition at line 126 of file p_whales.h.

◆ spaceDim

const int custom::whales::spaceDim = 2

The dimension of the phase space.

◆ spaceOffset

const double custom::whales::spaceOffset[spaceDim] = {0.0, 0.0}

An array which keeps the offset of the rectangular area in the phase space that contains the invariant sets of interest.

NOTE: The map is defined in such a way that all non-positive images are forced to be slightly positive; thus the phase space offset must not be negative.

const double custom::whales::spaceWidth[spaceDim] = {4.0, 4.0}

An array which keeps the width of the rectangular area in the phase space that contains the invariant sets of interest.

◆ spaceWrapping

const bool custom::whales::spaceWrapping[spaceDim] = {false, false}

periodic boundary conditions) in effect in the given directions?
