For most classes of signatures, there exists a set of complexity features that strongly correlates with signature effectiveness.
Complexity analysis of PARAFAC decomposition for CFO estimation is discussed in Section 5. Calculation of C ˆ ( q ) in Equation 22 requires inversion of A ˆ, which can be efficiently implemented using the fact that A is Vandermonde matrix and a closed-form solution for its inverse exists with a complexity of only O M u 2 operations[42].
The reason is that there exists a systematic connection between complexity and modifiability: the more complex a phenomenon is, the more modifiable it is.
Specifically, there exists an algorithm with complexity of that guarantees the finding of the optimal solution, however its high complexity limits its applicability for real-time computations and can be used only for benchmarking purposes.
In the field of software engineering, there exists a study about controlling the complexity of complex software systems by abstraction, using the agent concept called AOSE [8].
Therefore, there exists a tradeoff between performance and complexity of Capon, APES, CoSaMP and SABMP algorithm.
It should be noted that there exist a number of reduced complexity MAP-like detectors which are based upon searching trees [32, 33], which are not included in our comparison.
When an algorithmic solution to the problem exists, its complexity should be evaluated and be reduced as much as possible.
Our results suggest that a relationship exists between regulatory complexity and intergenic distance in S. cerevisiae and that this relationship accounts for the association between intergenic distance and essentiality.
Perhaps due to these complexities, there does not exist a computational model capable of estimating the time necessary to evolve a realistic CRM involving multiple TFs with distinct roles, under a range of population genetic and mechanistic assumptions.
