normalize	Whether to normalize return values in getState

Definition at line 60 of file DoublePole.h.

Member Function Documentation

failure()

bool shark::DoublePole::failure ( )

inline

Returns true when this pole is in an illegal position.

Definition at line 129 of file DoublePole.h.

Referenced by shark::MarkovPole< HiddenNeuron, OutputNeuron >::eval().

getJiggle()

double shark::DoublePole::getJiggle ( )

inline

Return "jiggle", abstract representation of how much the the cart oscillates.

Definition at line 143 of file DoublePole.h.

getState()

void shark::DoublePole::getState ( RealVector &  v )

inline

Place m_state in a vector.

Parameters

v	vector to place m_state in (assumed to be correct size already)

init() [1/2]

void shark::DoublePole::init ( double  state2init = 0.07 )

inline

Initialize with specific angle for large pole.

Parameters

state2init

initial pole angle (in radians)

Definition at line 101 of file DoublePole.h.

Referenced by shark::MarkovPole< HiddenNeuron, OutputNeuron >::eval(), and initDegree().

init() [2/2]

void shark::DoublePole::init ( double  a, double  b, double  c, double  d, double  e = 0., double  f = 0.  )

inline

Initialize full m_state.

Parameters

a	initial cart position
b	initial cart velocity
c	initial large pole angle (in radians)
d	initial large pole angular velocity
e	initial small pole angle (in radians)
f	initial small pole angular velocity

initDegree()

void shark::DoublePole::initDegree ( double  state2init )

inline

Initialize with specific angle for large pole.

Parameters

state2init

initial pole angle (in degrees)

References init().

move()

void shark::DoublePole::move ( double  output )

inline

Move the pole with some force.

Parameters

output

Force to apply. Expects values in [0,1], where values below 0.5 indicate applying force towards the left side and values above indicate force towards the right.
