java.lang.String	keyword() For the CodeSimian language as a String. CodeSimian language keyword, like "+" "*" "max" ">" etc. Override this function if you want to specify a keyword other than how I derive them from the class name, like + for Add. Some CSs might never be intended to be used in the language by their keyword. The best example (4/05) is Num, because it is used in the language like "3.4" instead of "num()".
int	minP() For DForProxy(). Minimum number of parameters in param[] needed to call DForProxy(). Defines which indexs of param[] DForProxy() can use. Functions with a different number of parameters must override this. OVERRIDE THIS FUNCTION IF EXEC USES A DIFFERENT NUMBER OF PARAMETERS. Default is 1.

Field Detail

chanceMustFixNetwork

protected double chanceMustFixNetwork

costs a lot to fix the network. Fixing is mostly updating params of parents of input nodes that are replaced. Exec() calls setInputNodesValues(P(1)), which fixes the network if necessary. This is the chance that between one call of DForProxy() and the next, the network will have to be fixed. Starts at .01 and averages (with exponential decay) the actual frequency that fixing occurs.

execCount

protected long execCount

Method Detail

DForProxy

public double DForProxy()

Description copied from class: CS

Execute this CS and cast to double.

D() and DForProxy() are the 2 most important functions in CS. They execute this CS. All other execute functions, by default, return DForProxy cast to their own type.

For example, J() calls the proxy which calls JForProxy() which calls DForProxy(). D() calls the proxy which calls DForProxy().

By default, all other primitive EXECUTE functions defer to D.
Functions that EXECUTE this CS: L(Class) L(int,Class,int) Z() B() C() S() I() J() F() D() V()

Specified by:

DForProxy in class DefaultCS

minP

public int minP()

Description copied from class: DefaultCS

For DForProxy().
Minimum number of parameters in param[] needed to call DForProxy().
Defines which indexs of param[] DForProxy() can use.
Functions with a different number of parameters must override this.
OVERRIDE THIS FUNCTION IF EXEC USES A DIFFERENT NUMBER OF PARAMETERS.
Default is 1.

Overrides:

minP in class DefaultCS

keyword

public java.lang.String keyword()

Description copied from class: DefaultCS

For the CodeSimian language as a String.
CodeSimian language keyword, like "+" "*" "max" ">" etc.

Override this function if you want to specify a keyword other than how I derive them from the class name, like + for Add.

Some CSs might never be intended to be used in the language by their keyword.
The best example (4/05) is Num, because it is used in the language like "3.4" instead of "num()".
Default: Returns class name, minus package name (and its dots), and change the first letter to lowercase.

For example, CS.MaxParams does not override keyword(), which returns "maxP".

Overrides:

keyword in class DefaultCS

See Also:

CS.parent(), CS.newInstance(), CS.name()

description

public java.lang.String description()

Description copied from class: CS

a short description of this CS, shorter than the javadoc, but long enough to tell what the params are for. Example use: in automatically generated webpages for CodeSimian. Example: "returns sum of all params" for Add.

Overrides:

description in class DefaultCS

cost

public double cost()

Description copied from class: CS

cost() should be changed to return a float, and should be renamed to costToExecute()

cost of EXECUTING this CS, not including any CSs it executes recursively. The INTERNAL cost.

One unit of myFuel() costs cost() units of fuel(). Beware of CSs that counterfeit fuel.

Returns 1 by default.

Overrides:

cost in class CS

setInputNodesValues

public boolean setInputNodesValues(CS inputValuesList)

input nodes are the first inputValuesList.length quantity of P(2)'s params. If can not set them with setD, replaces them with BayesNode instances that have a conditional-probability list size 2 (to specify the node's returned chance) (contains inputValuesList.P(p).D() preceded by 1 minus that) so their values are easy to set, and updates the parents' params to point to the new input nodes. Returns true if set all the values, including if they were set by being replaced.
