- 2\$\begingroup\$ The numbers for (10, 2) and (11, 2) are incorrect since both can be colored with 16 colors (the coloring is to xor together the indices of 1s, so color(1,1,1,0,1,0,0,0,0,0) would be 0^1^2^4). \$\endgroup\$gsitcia– gsitcia2023-07-26 12:04:03 +00:00Commented Jul 26, 2023 at 12:04
- \$\begingroup\$ @gsitcia I checked and wolfram engine does report 17 for 10,2. I can't really understand the code though. Do you think it isn't solving the right problem? \$\endgroup\$Simd– Simd2023-07-27 17:43:28 +00:00Commented Jul 27, 2023 at 17:43
- \$\begingroup\$ I am not sure why but it does seem your code is giving some wrong answers. \$\endgroup\$Simd– Simd2023-07-27 19:03:41 +00:00Commented Jul 27, 2023 at 19:03
- \$\begingroup\$ Mystery solved by a comment at mathematica.stackexchange.com/questions/288133/… . VertexChromaticNumber doesn't give the optimal answer. \$\endgroup\$Simd– Simd2023-07-27 21:57:45 +00:00Commented Jul 27, 2023 at 21:57

How to Edit
- Correct minor typos or mistakes

- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. code-golf), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
