PHP code is not being executed, instead code shows on the page

266 58 I'm trying to execute some PHP code on a project (using Dreamweaver) but the code isn't being run. When I check the source code, the PHP code appears as HTML tags (I can see it in the source code). Apache is running properly (I'm working with XAMPP), the PHP pages are being opened properly but the PHP code isn't being executed. Does someone have a suggestion about what is happening?

Cardinality of the set of algorithms

Image
15 3 $begingroup$ Someone in a discussion brought up that (he reckons) there can be at least continuum number of strategies to approach a specific problem. The specific problem was trading strategies (not algorithms but strategies) but I think thats beside the point for my question. This got me thinking about the cardinality of the set of algorithms. I have been searching around a bit but have come up with nothing. I've been thinking that, since turing machines operate with a finite set of alphabet and the tape has to be indexable thus countable, it's impossible to have uncountable number of algorithms. My set theory is admittedly rusty so I am not certain at all my reasoning is valid and I probably wouldn't be able to prove it, but it's an interesting thought. What is the cardinality of the set of algorithms? algorithms turing-machines combinatorics share | cite | improve this question edited Aug 28 '18 at 13:59 Raphael ♦ 57.8k 24...
