Variable Documentation

◆ compareMorseOrdering

const bool custom::duffing::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 171 of file p_duffing.h.

◆ finalDepth

const int custom::duffing::finalDepth = 9

The final depth of subdivisions in the phase space.

Definition at line 55 of file p_duffing.h.

◆ ignoreIsolationForConleyIndex

const bool custom::duffing::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 186 of file p_duffing.h.

◆ ignoreIsolationForContinuation

const bool custom::duffing::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 178 of file p_duffing.h.

◆ initialDepth

const int custom::duffing::initialDepth = 7

The initial depth of subdivisions in the phase space.

Definition at line 52 of file p_duffing.h.

◆ maxImageDiameter

const int custom::duffing::maxImageDiameter = 4000

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 129 of file p_duffing.h.

◆ maxImageVolume

const int custom::duffing::maxImageVolume = 40000

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 134 of file p_duffing.h.

◆ maxIndexPairSize

const int custom::duffing::maxIndexPairSize = 1200000

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 143 of file p_duffing.h.

◆ maxJoinConnection

const int custom::duffing::maxJoinConnection = 1000

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

Definition at line 157 of file p_duffing.h.

◆ maxJoinDistance

const int custom::duffing::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 161 of file p_duffing.h.

◆ maxJoinSize

const int custom::duffing::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 153 of file p_duffing.h.

◆ maxRefineSize0

const int custom::duffing::maxRefineSize0 = 200000

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 114 of file p_duffing.h.

◆ maxRefineSize1

const int custom::duffing::maxRefineSize1 = 20000

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 119 of file p_duffing.h.

◆ paramCount

const int custom::duffing::paramCount = 2

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

Definition at line 79 of file p_duffing.h.

◆ paramDim

const int custom::duffing::paramDim = 2

The dimension of the parameter space to iterate.

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

Definition at line 64 of file p_duffing.h.

◆ paramLeft

const double custom::duffing::paramLeft[paramCount] = {0.25, 0.3}

The left bounds on the parameters.

Definition at line 82 of file p_duffing.h.

◆ paramRight

const double custom::duffing::paramRight[paramCount] = {0.25, 0.3}

The right bounds on the parameters.

Definition at line 85 of file p_duffing.h.

◆ paramSelect

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

The numbers of parameters to subdivide.

Definition at line 71 of file p_duffing.h.

◆ paramSubdiv

const short int custom::duffing::paramSubdiv[paramDim] = {1, 1}

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 68 of file p_duffing.h.

◆ refineDepth

const int custom::duffing::refineDepth = 5

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 109 of file p_duffing.h.

◆ spaceDim

const int custom::duffing::spaceDim = 2

The dimension of the phase space.

const double custom::duffing::spaceOffset[spaceDim] = {-2, -2}

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

Definition at line 94 of file p_duffing.h.

◆ spaceWidth

const double custom::duffing::spaceWidth[spaceDim] = {4, 4}

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

Definition at line 98 of file p_duffing.h.

◆ spaceWrapping

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

Is space wrapping (a.k.a.

periodic boundary conditions) in effect in the given directions?
