I just started reading some papers (Computer Science, specifically Computer Vision) and thought "now let's look at the source code" and was quite astonished that most of the papers don't have any source code implementing the described methods to look at, while claiming some performance or being better than other papers.

How do these papers get accepted in journals / conferences? Do people have to submit their source code privately to the reviewers at least, so that they can reproduce the experiment if possible.

Do most journals / conferences just "trust" that people who submit the paper really implemented the theory and got those exact results?

I always had this idea that any experiment should be reproducible by others else it's not scientific justified. Been wondering about this the last few days.


Question: Why do I have to update to the most recent iOS version?
Answer: Apple has decided to remove previous versions when a new (replacement) is released.

You could scan the web and find other versions from someone else but not from Apple.
