Search Strategies.

The abstract base class of any user-defined class that Alps has to know about in order to encode/deco...
Node pool is used to store the nodes to be processed.
void setNodeSelection(AlpsSearchStrategy< AlpsTreeNode * > &compare)
Set strategy and resort heap.
void popKnowledge()
Remove the node with highest priority from the pool.
AlpsNodePool(AlpsSearchType type)
int getNumKnowledges() const
Query the number of nodes in the node pool.
double getBestKnowledgeValue() const
Get the "best value" of the nodes in node pool.
void deleteGuts()
Delete all the nodes in the pool and free memory.
void addKnowledge(AlpsKnowledge *node, double priority)
Remove the node with highest priority from the pool and the elite list.
std::pair< AlpsKnowledge *, double > getKnowledge() const
Get the node with highest priority.
AlpsTreeNode * getBestNode() const
Get the "best" nodes in node pool.
const AlpsPriorityQueue< AlpsTreeNode * > & getCandidateList() const
Get a constant reference to the priority queue that stores nodes.
void clear()
Remove all the nodes in the pool (does not free memory).
bool hasKnowledge() const
Check whether there are still nodes in the node pool.
bool empty() const
Return true for an empty vector.
const std::vector< T > & getContainer() const
Return a const reference to the container.
void clear()
Remove all elements from the vector.
void setComparison(AlpsSearchStrategy< T > &c)
Set comparison function and resort heap.
size_t size() const
Return the size of the vector.
void pop()
Remove the top element from the heap.
T top() const
Return the top element of the heap.
void push(T x)
Add a element to the heap.
This class holds one node of the search tree.
double getQuality() const
Query/set the quality of the node.
