Exact Inverse Polynomials

Exact Inverse Polynomials

A Free, Powerful, Even-Order Polynomial Coefficient Generator: exact by default to: 8th order & 2,000+ coefficients & real (non-exact) by custom configuration to: 20th order & 2,000+ coefficients The enabling math & tech:Computing adjoints and determinants involve no division; hence any full-rank matrix with integer coefficients has an inverse with exact rational coefficients. &Real16 (128-bit) variables have 31 significant digits; which supports tracking integer values up to 1 octillion. Adjoint integers grow faster than the determinant integers. My (this) cookbook…

Rules/Referees/Replays/ Rulebook – R4 – Justice

Rules/Referees/Replays/ Rulebook – R4 – Justice

Can justice be administered as fairly as competitive sports are refereed? Here’s the link to my one-page paper which advocates trying to go there: http://ftp.setterholm.com/WorldPeace/R4-Justice.pdf 2021.09.11: Most American judges and lawyers who enjoy watching sporting events can grasp that clear, uniformly-enforced rules allow games to progress in a timely & enjoyable manner. If, instead, there were legal systems – rather than enforced rules – sporting events would be undisciplined, dangerous, interrupted, (i.e.: insane) wastes of time on un-level playing fields….

Epidemic De-Quarantine Strategy

Epidemic De-Quarantine Strategy

I thought about a presentation given by a Nobel-Prize-winning scientist at The Nobel Conference XXXVII at Gustavus Adolphus College in St. Peter, MN in early October 2001; as a result, I wrote the following letter to the CDC in Atlanta. None of the four paths by which I attempted to deliver the letter resulted in a reply from any of the recipients or the CDC itself. Here’s the letter: ————————————————- Date: October 25, 2001 To: The Center for Disease Control,…

Greed : Hurricane Analogy

Greed : Hurricane Analogy

Earlier today via email I introduced this one-page paper to the President of Yale: ————— In the /WorldPeace subdirectory of www.setterholm.com ‘FILES’ tab, you’ll find the attached document. The direct link there is:  http://ftp.setterholm.com/WorldPeace/Greed&HurricaneAnalogy.pdf Your humanities faculty could consider ways to strengthen, and/or clarify, and/or  improve the message. As noted therein, the .pdf is available for unrestricted dissemination.

Best-Fitting the Continuous Parameters of Linear/Non-Linear Algorithmic Models of Arbitrarily Large Datasets with Extreme Accuracy “Tweaks” refer to the small changes of parameter values which are used to compute the numerical partial derivatives of an algorithmic model as the model converges on a best-fit of a given dataset. I called these analytics “Pseudoinverse System Analysis” (1983 – @ Honeywell MavD, Minneapolis,MN) and used them professionally for 35+ years; in applied mathematics these algorithms are an approach to “linear & non-linear…

Trapping & Mass Producing Knowledge (1990)

Trapping & Mass Producing Knowledge (1990)

In January 2017 I retyped a paper which I had written in 1990 on a Commodore 64, into an MS Word .doc & hence to the following .pdf. (The 7th page is a 1991 letter from my freshman year Physics Professor. 26 years had passed between last attending his lectures and his reply to me… & that was about half way to ‘now’.) http://ftp.setterholm.com/1990+/Trapping&MPK.pdf My inspiration to ~republish came from an extraordinary observation: The (Jan-Feb 2017) Yale Alumni Magazine’s cover article is/was “The Next Four Years – 11…
