Inheritance diagram for ell::WalkAdaptive:
Detailed Description
WalkAdaptive defines:- an enum for the kind of adaptive walk
- a static function "walkAdaptive" which takes all neccesary params for an adaptive walk
- a virtual member function "walk" which does the same as "walkAdaptive" but substitutes the NeighborGentype of "walkAdaptive" with a member

| ell::WalkAdaptive::WalkAdaptive | ( | const NeighborGenType | ngt, | |
| const bool | isDegenerate = false | |||
| ) |
constructor for a WalkAdaptive object, takes the type of walk
- Parameters:
-
ngt the type of the neighbor generator to use isDegenerate whether or not a degenerate landscape is in use and a 'lesser energy' check is not sufficient and the lexicographical order of the compressed representation is used as a tiebreaker (equal E).

This function implements a generic walk starting from State start. The properties of this search are defined by the implementations of NeighborhoodGenerator, StateAcceptor WalkAbortionCriterion and StateCollector.
- Parameters:
-
start the begin of the walk scWalk the StateCollector each step of the walk is added to ng the NeighborGenerator used to get the neighbor list of the last walk State to generate the next possible steps sa the StateAcceptor that decides if a step is accepted or rejected wac the walk abortion criterion that decides if the end of the walk has been reached or a further step is to do scRejected the StateCollector each rejected possible step is added to
- Returns:
- the modified scWalk StateCollector
| StateCollector * ell::WalkAdaptive::walk | ( | const State *const | start, | |
| StateCollector *const | scWalk, | |||

| ) | const [virtual] |
pure virtual function, s is start state
- Parameters:
-
start the begin of the walk scWalk the StateCollector each step of the walk is added to scRejected the StateCollector each rejected possible step is added to
- Returns:
- the modified scWalk StateCollector

| ) | [static] |
This static function implements an adaptive walk starting from State start by executing Walk::walk.
- Parameters:
-
start the begin of the walk scWalk the StateCollector each step of the walk is added to ngt the type of the neighbor generator to use scRejected the StateCollector each rejected possible step is added to isDegenerate whether or not a degenerate landscape is in use and a 'lesser energy' check is not sufficient and the lexicographical order of the compressed representation is used as a tiebreaker (equal E).
- Returns:
- the modified scWalk StateCollector
