As Valtr (1998) showed, the set system derived from an art gallery problem has bounded VC dimension, allowing the application of set cover algorithms based on ε-nets whose approximation ratio is the logarithm of the optimal number of guards rather than of the number of polygon vertices. [12]
BET model of multilayer adsorption, that is, a random distribution of sites covered by one, two, three, etc., adsorbate molecules. The concept of the theory is an extension of the Langmuir theory, which is a theory for monolayer molecular adsorption, to multilayer adsorption with the following hypotheses:
If the operator was self-adjoint, =, the direct state equation and the adjoint state equation would have the same left-hand side. In the goal of never inverting a matrix, which is a very slow process numerically, a LU decomposition can be used instead to solve the state equation, in O ( m 3 ) {\displaystyle O(m^{3})} operations for the ...
A Python 3 based simulation using Matplotlib to sketch Buffon's needle experiment with the parameters t = 5.0, l = 2.6. Observe the calculated value of π (y-axis) approaching 3.14 as the number of tosses (x-axis) approaches infinity. In the first, simpler case above, the formula obtained for the probability P can be rearranged to
Among the fast food giants, McDonald's is making a splash with its new value platform starting on Jan. 7, its first national value offering since 2018.Bernstein analyst Danilo Gargiulo called it a ...

Fields of interest include a given paper model's flat-foldability (whether the model can be flattened without damaging it), and the use of paper folds to solve mathematical equations up to the third order. [1] Computational origami is a recent branch of computer science that
