A postordering is a list of the vertices in the order that they were last visited by the algorithm. A postordering of an expression tree is the expression in reverse Polish notation. A reverse preordering is the reverse of a preordering, i.e. a list of the vertices in the opposite order of their first visit. Reverse preordering is not the same ...
The first list was published in 1977 and included 208 medications. [8] [2] [9] The WHO updates the list every two years. [10] There are 306 medications in the 14th list in 2005, [11] 410 in the 19th list in 2015, [10] 433 in the 20th list in 2017, [12] [13] 460 in the 21st list in 2019, [14] [15] [16] and 479 in the 22nd list in 2021.

Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic notation.
A modification of the Turing test wherein the objective of one or more of the roles have been reversed between machines and humans is termed a reverse Turing test. An example is implied in the work of psychoanalyst Wilfred Bion, [105] who was particularly fascinated by the "storm" that resulted from the encounter of one mind by another.
CNN layers arranged in 3 dimensions. For example, in CIFAR-10, images are only of size 32×32×3 (32 wide, 32 high, 3 color channels), so a single fully connected neuron in the first hidden layer of a regular neural network would have 32*32*3 = 3,072 weights. A 200×200 image, however, would lead to neurons that have 200*200*3 = 120,000 weights.
