I'd like to know how I can search by keywords for commands that I entered earlier in the SageMath terminal.
Thanks in advance!mcmugFri, 20 Mar 2020 06:48:58 +0100https://ask.sagemath.org/question/50308/Scatter search optimisationhttps://ask.sagemath.org/question/39655/scatter-search-optimisation/Hi all,
Does Sage offer something similar to the scatter search algorithms (Global Optimisation Toolbox) in Matlab? I looked through Sage documentation and through this forum but couldn't find a comprehensive answer.
Bit of background: I have a model with 6 parameters that together govern two probability distributions, looking to minimise error between calculated output and a target consisting of 4 variables. The probability distribution interacts with 1,000 - 100,000 data points to give a yes/no decision for each so they can be included/excluded in a sub-sample of data.
Excel (Evolutionary Solver) runs this in 1 - 24hr (admittedly on a 64Gb ram/12 core work station) so understandably I would like to speed this up. Python looks a sensible way to go, which brought me to Sage, but I got stuck trying to find out what optimisation algorithms are available.

When I search for documentation: "sage intersection of lists"
Most of the results are similar to:

**FIX:** Google Search Help* says that the sage webmaster needs to:
Create a "Google Webmasters Tools Account" - https://www.google.com/webmasters/tools/
then use the Fetch tool to get the spiders to you site so it can be indexed correctly -

For example, when searching for implicit_plot3d keywords, I tried using help(), tried going all over a Google Search, and tried going to the Sage documentation, but I could only find a partial list. Some of the examples used a keyword called "gradient", yet I could not find this in any keyword list for the function. Is there a way that I can take any Sage function, and see *all* of the optional keywords?themathman303Fri, 26 Sep 2014 05:37:37 +0200https://ask.sagemath.org/question/24288/Searching local HTML Docs with Chrome browser doesn't find anything, everhttps://ask.sagemath.org/question/10118/searching-local-html-docs-with-chrome-browser-doesnt-find-anything-ever/Using locally generated documentation ("make doc" in install dir), the Chrome browser search feature doesn't ever find anything. It used to work, but I don't know when it broke.
My local browser URLs:
file:///usr/local/src/sage/sage-5.9/devel/sage/doc/output/html/en/reference/search.html?q=lfsr
file:///usr/local/src/sage/sage-5.9/devel/sage-main/doc/output/html/en/reference/search.html?q=lfsr
... only show `Searching ...` forever.
This URL returns with doc references quickly.
http://www.sagemath.org/doc/reference/search.html?q=lfsr
What could be blocking my local doc searches?
Where can I look to start debugging?
Interestingly, Firefox works fine.

Since beginning using Sage, I have often been in the position that I need to find a specific algorithm for solving some problem. I might or might not already know that Sage has _some_ algorithm for doing it, but I want this one (for some reason). Is there an index or an easy way to search for this? The times I have tried using the search bar of sagemath.org, it has mostly been irrelevant posts, while a search on google like "<algorithm-name> site:sagemath.org" can give a bit as it also searches through the comments of the source code; but this is not very user-friendly, and it can take some time from finding some comment in a file, to know how to actually invoke specifically that code.
An example of this is the Berlekamp-Zassenhaus algorithm for factorising polynomials over integers.jsrnThu, 19 Aug 2010 03:49:49 +0200https://ask.sagemath.org/question/7580/
