Combinatorial search algorithms

The greedy descriptor is shown in Tables 7.7 and 7.8. The full combinatorial search algorithm (Tables 7.9 and 7.10) finds many similar semiempirical descriptors throughout the many types of configurations, among which the descriptor of Tables 7.9 and 7.10 has been chosen. The correlation vector to obtain Fig. 7.7 is,... 

The greedy (Tables 7.7 and 7.8) and complete combinatorial search algorithm (Tables 7.9 and 7.10) consider acetonitrile a strong outlier and take advantage of the two-valued (f>(P, 1) symmetry parameter that zeroes all indices whose properties have /t = 0, while leaves them unchanged if /t 0, i.e., for /t = 0, 4>-x = 0, while for II 0, (p-x = X- Th optimal full combinatorial descriptor with an improved r but is shown in Tables 7.9 and 7.10, while in Tables 7.11 and 7.12 is shown the corresponding zero-level description, which seems not excessively bad even if the aid of the non-random (f> ad hoc index plays a no minor role. The correlation vector of descriptor in Table 7.9, with whom Fig. 7.11 has been obtained, is,...

Although combiBUILD has been shown to be useful when the binding orientation of the scaffold is known, that is not always the case. The combinatorial DOCK algorithm has been developed as a more general tool for examining virtual libraries [52], Combinatorial DOCK places more emphasis on searching orientational space, that is how possible combinatorial compounds are oriented in the active site, and less emphasis on searching conformational space.

Descriptors based on pattern functions are helpful tools for a quick recognition of substructures. A pattern-search algorithm based on binary pattern descriptors can then be used for substructure search. However, patterns and other characteristics of descriptors that seem to indicate unique features should be investigated carefully. With these descriptors 3D similarity searches for complete structures or substructures in large databases are possible and computationally very efficient. In addition, descriptors can serve as the basis for a measure for the diversity of compounds in large data sets, a topic that is of high interest in combinatorial chemistry. 

The Joint Entropy-based Diversity Analysis (JEDA) is a method to select representative subsets of compounds from combinatorial libraries by using a scoring function based on the Shannon s entropy and implemented in a probabilistic search algorithm [Landon and Schaus, 2006].
