Get the parent of a given node.
In a general case, this would be given by a table, for balanced trees one can use a simple formula. The question is what to do with the root: should the function return 0, -1, or throw an exception?
Implemented in FlopSmiEx::TwoStageTree, and FlopSmiEx::BinTreeStruct.

Get the number of stages.

Get the number of scenarios = the number of leaves.
Definition at line 53 of file scen-tree_struct.hpp.
|
pure virtual |
Get probability of a given scenarios.
Implemented in FlopSmiEx::TwoStageTree, and FlopSmiEx::BinTreeStruct.
|
pure virtual |
Get the vector of nodes of a given scenarios.
Implemented in FlopSmiEx::TwoStageTree, and FlopSmiEx::BinTreeStruct.
|
inline |
Get the vector of nodes of a core scenario - just a wrapper.
Definition at line 62 of file scen-tree_struct.hpp.
|
pure virtual |
Get vector of nodes of a next scenario in the list.
This assumes that the class itself will keep track of the calls and hence knows what is the next scenario. This is used for Smi, when each scenario is described as a difference from a given parent scenario.
- Parameters
-
[out] scen number of the new scenario [out] parentScen parent scenario [out] branchStage stage where scen diverges from parentScen [out] prob probability of the new scenario
- Returns
- vector of node indices of the new scen, NULL at the end
Implemented in FlopSmiEx::TwoStageTree, and FlopSmiEx::BinTreeStruct.
