Fitness, aging and neurocognitive function
Neurobiology of Aging, 2005In this manuscript we provide a brief review of the recent literature that has examined the relationship among fitness training, cognition and brain. We began with a discussion of the non-human animal literature that has examined the relationship among these factors.

According to historical theories of biological function, a trait's function is determined by natural selection in the past. I argue that, in addition to historical functions, ahistorical functions ought to be recognized. I propose a theory of biological function which accommodates both.

Evolving Fitness Landscapes with Complementary Fitness Functions
2020Given an optimization problem, local search algorithms may fail to reach optimal solutions when faced to difficult and unsuitable fitness landscapes. Climbing based optimization is sensitive to unexpected distribution of local optima. In this paper, we aim at modifying the initial fitness landscape of a problem in order to better fit climbing ...

After designing a solution, you must evaluate your design by using the fitness function to ensure it can solve the problems under consideration. To check the functional requirements fitness, you might be using test-driven development, but what about the “-ilities”? How will you check the fitness function for the “-ilities”?

Density-functional theory vs density-functional fits
The Journal of Chemical Physics, 2022Kohn–Sham density-functional theory (DFT), the predominant framework for electronic structure computations in chemistry today, has undergone considerable evolution in the past few decades. The earliest DFT approximations were based on uniform electron gas models completely free of empirical parameters. Tremendous improvements were made by incorporating

Biochemistry![Figure][1] CREDIT: DUNHAM ET AL., EMBO J. 28 , 10.1038/EMBOJ.2009.120 (2009) In bacteria, low–copy number plasmids provide a model system for studying the segregation of DNA into daughter cells—partitioning requires only a centromere-like DNA site, a partition NTPase, and a centromere-binding protein.

Fitting Density Functions with Polynomials
Applied Statistics, 1992Summary: A robust procedure is developed for estimating density functions from data. It requires the existence of a parametric function, called the key function, to give a first approximation to the density and then improves the fit using polynomial adjustments.

Nonpolynomial fitting of multiparameter functions
Physical Review E, 1996A stochastic self-regulating simulated annealing optimization method is presented, and compared to other optimization methods such as the simplex, steepest descent, and the recently proposed fast fitting method by Penna [Phys. Rev. E 51, R1 (1995)].

In online communities a few experts are able to help a large number of help-seekers -- whether in QA (2) Functional -- There was little duplication of help-giving effort; and, (3) Fitting -- Initial responses were of high quality and reduced the need for further clarifications and corrections; high quality responses were provided earlier in the thread.

Evolutionary Music and Fitness Functions
2002Is it possible to obtain pleasant evolved music by means of a fitness function, without human intervention? In this work a method based on a genetic algorithm to produce automatic music is presented. In particular we developed a fitness function based on consonance, which allows to evaluate the “pleasantness” of a sequence of notes generated by an ...
