@Preben Alsholm OK... It's nice to know your personal reason for deleting my answer.

A few additional and final questions:

1. What is wrong with choosing one's own answer as the best in the absence of any other answers? Basically, this opportunity is open to anyone. If this is a bad habit, turn this option off.

2. What is irrelevant about my deleted answer? I'm just replying that Maplesoft is obviously ignoring all the current information about the terribly outdated Maple online help. That is all!!!

3. It is truly alarming that some highly respected people are willing to delete anything that does not align with their personal philosophy. Is the fact that Maplesoft hasn't updated the online help for almost 2 years ok with you?

4.So this isn't abuse, am I right?

OK ... somebody highly reputed deleted my answer!? Is that really common practice here?

I just comment the situation, that after week of escalation of the problem still no progress with outdated on-line help :(

What I did so wrong ... to be deleted???

@Carl Love in a case (1+... ) > 1 the supremum is Infinity. 

@Preben Alsholm But definitely answer "0" is not a right response for unrestricted case!!!

More sophisticated answer by MMA:

Maximize::natt: The maximum is not attained at any point satisfying the given constraints. 

Another bug from many, many ... others :(

Is there any serious reason to trust any of Maple's results?

Maple needs to be a reliable tool for symbolic math, not a bug-finding quiz...

@Christopher2222 same problem on the Ubuntu 22.04 and Linux Mint 21.1 Cinnamon desktop

@Carl Love This sentence in particular is very telling:

"However, for you to call it abuse is abusive, and the only reason that I'm not even more annoyed by your Question is that perhaps you thought that this was an official customer-support channel rather than a public forum. If you show disrespect to acer again, I'll delete it."

Nobody here shows any kind of disrespect!

@Scot Gould I can confirm that! Maple web-based help is outdated since 2021?! 

@tomleslie Or I can flip through the printed version of the manual, right?

@Christopher2222 

"I find it hard to believe that the online help pages could have gone through all of 2022 without being updated." 

I can't believe it either!!!

@Christopher2222 Same situation on Windows ...

The exactly same problem on Maple 2023 (Linux)...!!??

Looks like the @acer is not in a good mood lately :)

MaplePrimes is actually a community forum (with minimal ties to Maplesoft support) and some highly reputed people can do whatever they want. The only option is to contact the official Maple support directly. This problem is common on almost all community forums ... unfortunately this is a common practice!?

@Mariusz Iwaniuk Simply, bacause I want to know how Maple compares with Mathematica on this topic. 

@Christopher2222 The same problem with on-line Maple help WWW pages!!!??? Still version 2021 🤣 See here. 

Is that normal???
