True.

In those examples it's not actually failing at doing what it's supposed to do. But maybe that's not what you meant.

No, I worded it poorly. What I'm saying is that greedy algorithms, in the process of navigating only local optima, are almost guaranteed to overlook global optima in any sufficiently complex problem space. What I should have said was "deceived" not "failed." Which is why we have meta-heuristics, of course!

This doesn't apply to Dijkstra's algorithm. It can be proven to be correct* on any weighted, directed graph. You might even call it the poster boy for correct greedy algorithms.

* By which I mean that it finds the optimal solution, since it is not a heuristic.

Yeah, that's pretty much exactly how I remember it in my minds eye. How odd. I'd become convinced my memory was entirely faulty on the subject.

I still remember daft amounts of how to use assembly to draw vga graphics with some alacrity. That's not been needed for quite some time. Fairly much forgotten any spectrum era assembly though.

Exactly. Star Wars is a licence to spend $200+m making a film that hopefully won't suck. King is a licence to sit back and feel your arse grow as the money rolls in.

Not infrequently I have people print stuff, bring it up to me and ask me to put it on the Internet. I politely explain that they need to email it to me instead.

I used to work somewhere that introduced a paperless office and brand new IT system.

This system involved printing out a useless confirmation on a side of A4 every time you booked something... Which happened every 3 or 4 minutes.

With 15+ staff, we went through reams of paper that all ended up in the recycling bin.

I once got talking to a GP practice where they were receiving the discharge summary letters generated by a system I made for the hospital. It's possible to configure their GP system to automatically receive the letters and use the NHS number to add them to relevant patient records. It emerged that these lot were printing them off before scanning them back and shredding the print in because the manual input part of the GP system would only accept jpegs. :facepalm:

We've had a couple of staff that insisted on printing out documents just to scan them in and save a copy.
They could never explain why this had to be done, but they were very sure that it should be so.

I would imagine that the various Star Wars games and merch make a lot more than a film is guaranteed to make; though the upcoming film will obviously make a bajillion dollars.

I bet that Star Wars is the better long term investment :)

King has already diversified beyond Candy Crush; it's already proven it can be the company producing the new and incredibly popular games (unlike Zynga.) That's going to have driven a huge amount of the valuation.

Three King games were top 10 grossing games on both the Apple App Store and Google Play Store in the U.S. for second quarter 2015, marking the Company's sixth consecutive quarter with at least three titles in the top 10 grossing games list on one or both of these major U.S. mobile platforms
