:::::::: Perhaps Wikipedia has installed a later build ? Tho even they have related problems – only yesterday I restored the lost visibility of one of the first three formulae on the Wiki page on Symmetric Difference, by pruning extraneous space out of its <math> tag ...

::::::::: Just checked – Wikipedia is using a slightly later build '''MediaWiki 1.28.0-wmf.20''' (vs Rosetta's '''MediaWiki 1.26.2''') so an upgrade might reduce the fragility of the '''<math>''' tag
::::::::: Cosmetic editing will still need to involve checking in both kinds of browsers [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 15:33, 24 September 2016 (UTC)

==Another transportation problem==
On tio, I modified a copy of [[Transportation_problem#REXX]] to start with
4 5 # of sources / # of demands
50 60 50 50 sources
30 20 70 30 60 demands
16 16 13 22 17 cost matrix
14 14 13 19 15
19 19 20 23 50
50 12 50 15 11
and found I also had to change the first Do i=1 To 5 in init to Do i=1 To 7, then it worked fine. Obviously it would be better to analyse the first line and then loop/read from 2 to (number of sources+3). It also strikes me the code on that page should actually be on [[Vogel%27s_approximation_method]] and maybe try stepping stone or something else on the tp page, jmo. --[[User:Petelomax|Pete Lomax]] ([[User talk:Petelomax|talk]]) 12:58, 10 December 2020 (UTC)
:Two problems or three:
I discovered Vogel's page only after I finisher this pgm. And my pgm does not properly work with Vogel's data :-(
<br>I am still trying to understand how to optimize :-(
<br>I don't know how t proüerly sign such a text.
<br>Anyway, thanks for caring :-) Walter
