However all of that depends on how you are going to use it. And even should include questioning business requirements as to why they think they need something in the first place.

I see what you’re saying, just because I don’t need that potentially useful information doesn’t mean a scenario where that information is being used could not be imagined. Thanks

This is basically what A* aims to avoid, trying to limit the searched area as much as possible while still guaranteeing an optimal result (as long as the requirements on the heuristic are met).

Write it yourself. Limitations will be, and Dijkstra solves some, not all.

..or just ask ChatGTP if it's homework.

We have learned that it is currently far from a reliable source for this kind of work.

Yes, we who support members in the Quick Answers[^] section of the website. We have been watching the solutions given using ChatGPT as plagiarised answers. Half the time it does not compile, and mostly when it does, it does not work.

Eddy just curious, your way of addressing is always so sketchy, do you always expect the other person to guess the second half of the thing you’re trying to say?

I address developers. If it sketchy, you're not.

Half a word is all you can get, since money on the line.

This is help wanted forum, when you provide feedback besides knowing stuff you also need the ability to explain it
You want me to wave my developer badge? I’m just a student. But that doesn’t mean I can’t make the difference between a good explanation and a bad one. This is our second encounter, I see you using the same style as previosely

Did you consider the option that you were right?

If something is important to you, it's a passion, right? So, we speak with passion, and wars break out over the placement of a newline in code. I'm not apologizing, and you have nothing to apologize for either.

I'd panic if someone told me I had to stand in front of a classroom again Laugh | :laugh:

..but seriously, write it yourself and start simpeler than Dijkstra. The easiest path-finding algo is to simply "try all nodes and measure them". That will cost a lot of memory and computing power, but it would work and the result is the optimal path. Go for it; every stop is a node, and we weigh distance.

Next step is to try to optimize that. I'm pretty sure you can eliminate all those paths that go the wrong way for a certain distance. Then write Dijkstra's algo.

Once you understand the optimization, you understand it's implications and limitations. So, asking that question means either you or the teacher is trying a shortcut. Maybe the teacher is right.

..but this approach works every time. Anything else is parroting a textbook IMO.

edit: You start with two rhetorical statements (two questions) one after the other, usually that’s not how an argument is made.
I had to say it.

> we speak with passion

In my opinion passion is one thing it has a positive meaning, lashing out by breaking the boundaries of politeness (which is what I did) is something else.

Ah. Now I understand the point you're making. So now the student is teaching me? I just write what comes to mind, sometimes emotion gets mixed in. I don't recognize the rhetorical question as one, just like I do not recognize passive-aggressive.

I've never had a real education, something I intend to remedy this year and which will take more than just "this" year. There's some area's where my skills could be improved upon, so to speak. See the first line in my sig for a hint why.

Given your reaction, you're ahead of me on that point. Take heart in that.

Not at all. We are all different and have our own way of expressing ourselves. Your argument might still be valid, however the way you express it makes it difficult( not impossible) to follow

Rather certain that almost everyone would be comfortable with the statement that Hitler's speeches were passionate. But many would not claim that the passion was positive.

Many would be wrong then.

You can hardly blame "passionate speaking" for the results.

I would consider the response concise and on point.

But however I can see that someone with less experience perhaps in forums and/or with development might not understand what was implied.

If you’re talking about the reply [2 Jan 23:48] , nothing unusual with that reply in its own right. When you corroborate that reply with what he said in the data base thread you will notice a gambling tendency. He’s providing feedback on questions that are not there.
In [2 Jan 23:48] he makes the assumption I did not write a Dijkstra implementation already, he has no grounds to make that assumption.

Again I’m not saying he’s doing it on purpose. However it’s difficult to cope when you’re trying to learn something and you’re only receiving evasive answers.
When the answer is 100 percent between the lines you can’t learn much

Conversations of any sort are always based on assumptions.

The post I read made sense to me as a response given to the post that I read. I understood immediately what he was saying.

But, as I said, that is likely due to the decades of experience that I have.

Calin Negru wrote:

The reality is that forums, all forums of any sort, cannot attempt to explain absolutely everything to every single question. There is not enough time in the universe.

And as an very specific example that you will encounter often is that responses, instead of answering the question, will attempt to explain why it should be done in a different manner. Those responses are in fact very often correct. And quite possibly are often correct even for the question asked. But sometimes there are reasons that the original post did not provide which mean they are wrong. So wasting everyone's time. But again that is a case of assumptions being made.
