I had the opportunity of interacting with Gu and Bob Bixby of GuRoBi(& CPLEX). Some of the most talented OR scientists.
I think your definition of Integer programming is not correct. Integer programming or Mixed Integer Programming assumes that the solution has the all or some variables, integers. Most of the Integer programming models are usually using binary variable to indicate decisions.

Further, I think you tried to describe Linear programming in the beginning of your post. But Linear programming searches the vertices of the polytope and not the edges.

The biggest issue with Integer programming is the lack of convexity of the solution space when compared to Linear programming. So the approach for solving them is very different compared to Linear programming. If I made any mistakes in my post, I welcome to be corrected.

Re:Adobe Acquires Photo-Editing Platform Aviary on Tuesday September 23, 2014 @01:18AM (#8354138)
I think a web based killer is very far away in the time line. I recently was trying to make a huge gird in Photoshop and my i7+10gbRAM computer was unable to handle it. I think very simple stuff like annotating and cropping/red-eye fix can be done but I think a web based photo editor will fail when huge performance is required.

By any chance, do you have a link to them?

Calling Stallman a jerk is definitely uncalled for. I personally think he is the epitome of everything that is right with the Computer Science. It is your prerogative to distribute the software however you like. Remember that Stallman created something which most of us can only sapire about.

Ask HN: Is it possible for anyone to be a mentor for me?

Hi! I am a beginner Cocoa developer and I would like someone to be a mentor for me. I just need someone who can tell me if I ask how a certain functionality can be achieved. I am decently good at objective-C and I am creating an open-source linear programming solver. I have the library ready and I just need someone who can guide me to create the GUI. I swear I am not going to ask you the basic...

How good is this book for a complete beginner? I am starting to learn C in my free time and I have no objective way to judge this book.
Re:Japanese Toilets: The Future Called 30 Years Ago on Friday April 04, 2014 @06:49AM (#7530444)
India. No offense taken. FWIW, I can afford toilet paper. I just don't use it as I am habituated to using my hand. In case you are wondering, I can guarantee that the number of people who use their hand to clean their bottoms is much more than the combined population of USA.
Re:Japanese Toilets: The Future Called 30 Years Ago on Friday April 04, 2014 @04:06AM (#7529954)
I still don't use toilet paper. I used one when I had access to it(in a hotel). I knew toilet paper existed as once when I saw it in movies or read about it.
Re:Japanese Toilets: The Future Called 30 Years Ago on Friday April 04, 2014 @01:02AM (#7529410)
You will probably hate me for giving some graphic details but I had never used Toilet paper for the first 21 years of my life.(I am 22 BTW). I didn't even use a bidet. Just my left hand and water. I know this might be considered very disgusting but it is very common from where I am.

Come on. It's not that bad. I know design is a subjective thing, but calling it a disaster is a bit too much, IMO.

Not to be that guy but regardless is the correct form. Irregardless is considered as non-standard or incorrect. But if you do know this, please don't mind this nitpick.
Re:Taking a second look at free fonts on Wednesday March 12, 2014 @08:41PM (#7389423)
I was a typesetter for sometime(never released a typeface officially) and during another recent discussion on typefaces, I heard about source code pro. I swear I told many people that consolas is the best mono-space font. But source-code pro changed it. It became my main coding font now and it is simply amazing.

I request everyone to try it.

Most important thing that comes to my mind is space. I have no idea about the size occupied by a single "batch" but I can say that two small ones require more space. One more thing is, maintaining one large "reactor" is easy when compared to 10 small ones.
Re:Clear Sans on Tuesday March 04, 2014 @11:22PM (#7345261)
I used to design typefaces as a hobby. It is not so easy. You might think that your typeface looks fine but some experienced typeface designer will rip your design to pieces saying the bowls are not smooth, the stems are not having consistent thickness etc(he is not wrong. I just didn't have the "eye" for spotting such things).

But as they say, practice makes man perfect. Good Luck.

It takes around 6-7 months to design just a "regular" typeface. Be patient if you ever take this up.

Re:Microsoft users, it's time to switch on Monday March 03, 2014 @06:21AM (#7333147)
I can only comment about MS office as I use it everyday at my office.

I can not think how Google's spreadsheet can replace Excel.

I have some thousands of rows on a single sheet and a spotty internet connection. If Google introduces a native, offline app, then i might switch.

Re:Poll: Do you encrypt your files? on Thursday February 13, 2014 @08:56PM (#7236353)
I Do Not encrypt any files. I have a desktop at my home and i never saw need to. Although I don't live in a first world country. So no first world problems.
Just to give a idea of how the salary structure works here. Suppose you are earning 50,000 per month, only 11,000 will be your basic, some 5000 will be your house rent. and another 5000 for some expenses and additional perks can be up to some 30000. So, they will earn only 11,000 pm instead of the 50,000. which won't even be sufficient to pay rent.
Anyway to talk to you by email? Your website is difficult to navigate

Is this true? I am from India and want to do a PhD in US. I thought the work opportunities of PhD gards is good.
