Orchesella simplex is a species of slender springtail in the family Entomobryidae. [1] [2]
In geometry, a simplex is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. The simplex is so-named because it represents the simplest possible polytope made with line segments in any given dimension.
In mathematics, a simplicial complex is a set composed of points, line segments, triangles, and their n-dimensional counterparts. Simplicial complexes should not be confused with the more abstract notion of a simplicial set appearing in modern simplicial homotopy theory. The purely combinatorial counterpart to a simplicial complex is an abstract simplicial complex. To distinguish a simplicial from an abstract simplicial complex, the former is often called a geometric simplicial complex.
The Nelder–Mead method is a numerical method used to find the minimum or maximum of an objective function in a multidimensional space. It is a direct search method and is often applied to nonlinear optimization problems for which derivatives may not be known. However, the Nelder–Mead technique is a heuristic search method that can converge to non-stationary points on problems that can be solved by alternative methods.
Orchesella is a genus of springtails belonging to the family Entomobryidae. This genus includes springtails with subdivided basal antennal segments.
Orchesella cincta is a species of springtail present in North America and Europe. They average 4 millimetres (0.16 in) in length, which is extremely large as most springtails don’t grow past 1 millimetre. The specific name cincta means "belted" and refers to the distinctive colouration of the third abdominal segment.
