The Evolutionary Computation 'Bestiary' is a highly critical and satirical catalog of metaphor-based meta-heuristic search algorithms, intended to document the "exuberance" and proliferation of methods inspired by a vast, eclectic range of natural, supernatural, human, and physical phenomena, including classics like Genetic Algorithms and Ant Colony Optimization alongside numerous examples such as African Buffalo Optimization, Al-Biruni Earth Radius, Black Widow Optimization, COVID-19 variations, Honey Badger Algorithm, Hippopotamus Optimization, and Zombie Survival Optimization. Maintained by Claus Aranha and Felipe Campelo, the resource explicitly disavows the quality of most listed methods, labeling them as "ridiculous" and largely a "useless waste of space," functioning as "The island of Doctor Moreau" to highlight a phase in the field's history over-reliant on metaphor rather than mathematics. The document strongly recommends reading several critical papers that expose the lack of rigor and novelty in many of these metaphor-driven techniques, while algorithms are included based on peer-review publication and naming the metaphor in the title or abstract, listing only the earliest known mention.

AI model trained on over ten million decisions from psychological experiments that can predict human behavior with unprecedented accuracy, even in entirely new situations it has never encountered before, potentially revolutionizing our understanding of human cognition and decision-making processes.

First theorized to exist back in the 1940s, the leftover glow from the Big Bang — also known as the cosmic microwave background, or CMB — was confirmed to exist back in the mid-1960s. Although many have questioned its interpretation and ultimate origin, its detailed properties not only confirm its emergence from a hot Big Bang, but provide many other cosmic insights. Yet still, even today, one huge cosmic mystery looms large: the Hubble tension. Here’s what we know about the CMB, plus what still remains to be discovered about our Universe.
