• 17:2717:27, 10 April 2025 diff hist 0 m Diamond norm →Semidefinite programming formulation: The original text used "min" in the semidefinite program, which would result in negative values of the purported "norm." I changed to "max," which ensures that the value is nonnegative. I don't have access to the second reference cited here, but https://arxiv.org/abs/0901.4709 (which has since been published formally) shows that a maximum is used. current Tag: Visual edit

• 17:4117:41, 23 December 2023 diff hist +272 List of diss tracks Clarified that Emmett wrote the original version of Dixie, but not the parodies thereof. I've added a specific example of someone who wrote a parody, but the academic paper that I reference notes that several parodies are known. I don't know the author of the parody that shows when searched for on YouTube. It might be possible to infer who that was by reading the paper I cite in more detail. Tag: Visual edit

• 11:3411:34, 13 September 2023 diff hist −22 m CUDA →Background: Sort algorithms are not fundamentally well-suited to GPUs. If one is sorting on a primitive data type (e.g., ints or doubles) then there are high-performance algorithms. However, general sort algorithms that rely on a comparison operation "a <= b" can involve computing nontrivial functions of (a, b). Unless all O(n^2) of these comparisons are made ahead of time there is no hope for doing this efficiently on a GPU. Tag: Visual edit

• 19:3119:31, 1 June 2023 diff hist +668 Convex optimization →Implementations: Renamed to "software". Clarified that the table contains a mix of software that implements algorithms and software that makes it easy to define and manipulate convex optimization models. Tag: Visual edit

• 05:5405:54, 10 February 2023 diff hist +1,672 La Croix Sparkling Water →Flavors: I added mention of a common experience where the Key Lime flavor is described as "skittles like". I know this is unusual information to include in Wikipedia, but I find it interesting and well-documented. For now I put this under a "receptions" subheading of "flavors". If someone would like to present this material differently, I'm all ears! Tags: Reverted use of deprecated (unreliable) source Visual edit

12 October 2021

• 16:2516:25, 12 October 2021 diff hist +6 m Generalized minimal residual method →The method: Corrected one sign error. Eliminated an undefined variable "z_n" that was used as shorthand in one place. Tag: Visual edit
• 16:1116:11, 12 October 2021 diff hist −47 m Generalized minimal residual method The attribution of GMRES versus MINRES was confusing. I reworded a couple of sentences. Tag: Visual edit

• 13:4413:44, 10 September 2021 diff hist 0 Tulsa race massacre Undid revision 1043363713 by 178.17.180.33 (talk) In the last edit, an anonymous user replaced every instance of "white" to "White", with the explanation that they "fixed racist things". The capitalization of "w" in "white" is a matter of style that article authors or the Wikipedia community should decide on. For example, the AP capitalizes "Black" but not "white". Further discussion should happen on the talk page. Tag: Undo

The slight modification here should improve clarity on this issue without loss of other information. If someone feels strongly about this edit, feel free to revert.
