The standard complexity classes of complexity theory do not allow for direct classification of most of the problems solved by heuristic search algorithms.
The alignment free methods correspond to a class of low complexity methods, which have a low temporal and spatial complexity in relation to the methods which requires a prior alignment.
With regard to hysteresis-loop bursters, the class of smallest complexity is subH/FLC (c16), which exists close to the codim-2 Bautin bifurcation as outlined by Golubitsky et al. Class SN/SH (c2) lives close to the codim-2 Saddle-Node-Loop bifurcation [17], but this bifurcation is not local and the lowest codimension singularity for this class is the codim-3 deg.
Another important class of network complexity measures is based on determining subgraphs of a network [51], [56].
In this paper, we present a class of low-complexity decimation filters for oversampled discrete-time signals.
As the 21 cases were designed for a pharmacotherapy introduction class, the level of complexity was simple (see Appendix 1 for an example).
The two ways in which strength can be increased in second-order theories of arithmetic is by allowing broader classes of substituends (complexity classes of formulae) in their axiom-scheme of comprehension, and in their axiom-scheme of mathematical induction.
The main advantage of the proposed algorithm is a class of quadratic time complexity as compared to the cubic one for the classical frequency weighted method, the major feature resulting from the application of analytical methods for calculation of factorizations for controllability and observability Gramians.
Because of complexity class of this problem that was categorized as NP-hard, two metaheurstic algorithms based on genetic and MPSO algorithms were developed to solve problems.
Percentage of cells occurring within each class, for all levels of complexity and time periods (a) training (1991 1995), (b) testing 1 (1991–2003), and (c) testing 2 (1995–2003).
