Heejin officially debuted with Loona as a full group on August 20, 2018 with the release of their debut EP . [ 12 ] On November 28, 2022, JTBC Entertainment News reported that nine members of Loona, including Heejin, had filed an application for a provisional injunction to suspend their exclusive contract with Blockberry Creative, following ...
The Steinhaus–Johnson–Trotter algorithm or Johnson–Trotter algorithm, also called plain changes, is an algorithm named after Hugo Steinhaus, Selmer M. Johnson and Hale F. Trotter that generates all of the permutations of elements. Each two adjacent permutations in the resulting sequence differ by swapping two adjacent permuted elements.
The decision version of set covering is NP-complete. It is one of Karp's 21 NP-complete problems shown to be NP-complete in 1972. The optimization/search version of set cover is NP-hard. [1] It is a problem "whose study has led to the development of fundamental techniques for the entire field" of approximation algorithms. [2]
Loona 1/3 (commonly stylized in all caps or LOOΠΔ 1/3) is the first sub-unit of South Korean girl group Loona, formed through a pre-debut project titled "Girl of the Month". The unit consists of four members: HeeJin, HyunJin, HaSeul, and ViVi. They debuted on March 13, 2017, with the extended play Love & Live.
A very strong version was used by Max Clausen in Richard Sorge's network in Japan, and by Alexander Foote in the Lucy spy ring in Switzerland. [1] A slightly weaker version was used by the Rote Kapelle network. [2] In both versions, the plaintext was first converted to digits by use of a straddling checkerboard rather than a Polybius square.
Skein was created by Bruce Schneier, Niels Ferguson, Stefan Lucks, Doug Whiting, Mihir Bellare, Tadayoshi Kohno, Jon Callas and Jesse Walker.. Skein is based on the Threefish tweakable block cipher compressed using Unique Block Iteration (UBI) chaining mode, a variant of the Matyas–Meyer–Oseas hash mode, [3] while leveraging an optional low-overhead argument-system for flexibility.
If there exists an equal partition of the inputs, then the optimal packing needs 2 bins; therefore, every algorithm with an approximation ratio smaller than 3 / 2 must return less than 3 bins, which must be 2 bins. In contrast, if there is no equal partition of the inputs, then the optimal packing needs at least 3 bins.
The original Whirlpool will be called Whirlpool-0, the first revision of Whirlpool will be called Whirlpool-T and the latest version will be called Whirlpool in the following test vectors. In the first revision in 2001, the S-box was changed from a randomly generated one with good cryptographic properties to one which has better cryptographic ...
