Тезаурус:
- The Thai medicinal plant Croton sublyratus , which is used in traditional medicine, has recently been found to contain the antiulcer acyclic terpenoid plaunotol ( 17 ) which is similar in structure to gefarnate.
- This structure is actually a graph rather than a tree, and is known as a Directed Acyclic Word Graph (dawg).
- This graph of vertices and edges is acyclic and directed.
- Details and results of comparisons between some implemented data structures were presented, and some methods of memory reduction such as tail-end compression and the use of a directed acyclic word graph were discussed.
- Directed acyclic word graphs
- It was concerned almost exclusively with acyclic "functionally simple" compounds ie acyclic compounds with only one type of functional group.
- Eight acyclic terpenes have been found in the plant which may have antiulcer activity.
- Factors taken into consideration are, in decreasing order of priority: minimisation of the number of free valences of the CRU; maximisation of the number of most preferred heteroatoms in the ring system; retaining the most preferred ring system; and choosing the longest chain for an acyclic CRU.
- However it does mean that the additional information can be removed from the look-up tree, which in turn means that a compression method can now be applied to the tree, such as utilising a directed acyclic word graph (section 3.2.5 and section 3.3.3).
- Several types of tree structures were implemented for comparison: a binary tree (section 3.2.2), a 26-way tree (section 3.2.3.2), a reduced memory tree (section 3.3.1), two linked list mixed-method trees (section 3.3.2), one using the 26-way tree structure, and the other using the reduced memory structure, a binary trie (section 3.2.3.3) and a directed acyclic word graph (section 3.2.5).
- The directed acyclic word graph (section 3.2.5 and section 3.3.3) is the optimal structure for saving memory, but no additional information can be stored for each word.
