My web applications have pages that display many static fields. I know that poor layout invariably leads to information overload and poor readability. My Question: Are there any best-practices or heuristics for laying out a screen that contains many static fields? Ordinarily, I would reference Bill Scott and Theresa Neil's excell...
I am not expecting a definite yes or no. Any knowledge you might have I will consider as an answer. private String CalculateCharge(Nullable<Decimal> bill, Nullable<Decimal> rate) { return ((bill ?? 0.0m) * (rate ?? 0.0m)).ToString("C"); } ...

As far as I know There are 4 ways to solve recurrence equations : 1- Recursion trees 2- Substitution 3 - Iteration 4 - Derivative We are asked to use Substitution, which we will need to guess a formula for output. I read from CLRS book that there is no magic to do this, i was curious if there are any heuristics to do this? I can certa...
When reading zipfiles (using Java ZipInputStream or any other library) from an unknown source is there any way of detecting which entries are "character data" (and if so the encoding) or "binary data". And, if binary, any way of determining any more information (MIME types, etc.) EDIT does the ByteOrderMark (BOM) occur in zipentries and...
I have thought of some heuristics for a big (higher dimensions) tic-tac-toe game. How do I check which of them are actually consistent? What is meant by consistency anyways? ...
A small (3x3, 4x4) tic-tac-toe can be easily solved by considering all the cases. But for example, you have a 30x30 tic-tac-toe. What algorithm would you use to decide the next best move in that case? Minimax + alpha-beta pruning is one way that I know. Is there some other way that is more efficient/not more efficient but cooler? ...
Are there any general heuristics, tips, tricks, or common design paradigms that can be employed to convert a recursive algorithm to an iterative one? I know it can be done, I'm wondering if there are practices worth keeping in mind when doing so. ...
I am planning to make a Bubblet game in Java, because I simply love the game. What can be used as a heuristic for the game? I will make it 30x30 or bigger, and I cannot figure out how to make the computer play the game efficiently... Can you suggest some idea? Thanks ...
I'm reading over my AI textbook and I'm curious about what the difference is between monotonicity and admissibility of heuristics (I know they aren't mutually exclusive). As far as I can tell, an admissible heuristic simply means you are ensured to get the shortest path to a solution if one exists. What I'm struggling with is the conc...
I'm trying to measure the popularity of a post but there's no current system in place that can do that so that means I have to create one. Can anyone guide me on creating a heuristic that measures popularity for a post? I'm assuming factors such as # of replies, # of views, age of post, sticky vs. non-sticky, etc. should play in as a fa...
http://lab.arc90.com/experiments/readability/ is a very handy tool for viewing cluttered newspaper, journal and blog pages in a very readable manner. It does this by using some heuristcis and finding the relevant main text of a web page. Its source code is also available at http://lab.arc90.com/experiments/readability/js/readability.js ...
For web sites that have username/password text input fields, the browser usually handily offers to remember them for you (in my case, Safari puts them in my OS X keychain). This simply does not happen with certain web sites. The first example that comes to mind is vBulletin forums. Meaning you can't use a complex/random password unless ...
Is there anyway to ensure the that the fewest number of turns heuristic is met by anything except a breadth first search? Perhaps some more explanation would help. I have a random graph, much like this: 0 1 1 1 2 3 4 5 6 7 9 a 5 b c 9 d e f f 9 9 g h i Starting in the top left corner, I need to know the fewest number of steps it wou...
I know there are some scheduling problems out there that are NP-hard/NP-complete ... however, none of them are stated in such a way to show this situation is also NP. If you have a set of tasks constrained to a startAfter, startBy, and duration all trying to use a single resource ... can you resolve a schedule or identify that it cannot...
Sorry if this seems like a hazy question but it's something that's been bugging me for a little while. In my day job, some of the code I write gets pretty complex. Not that it's usually very technical but the problem domain itself is a complex matter dealing with spacial data amongst many other things. I'm pretty sure my NDA would proh...
I'm new to the whole traveling-salesman problem as well as stackoverflow so let me know if I say something that isn't quite right. Intro: I'm trying to code a profit/time-optimized multiple-trade algorithm for a game which involves multiple cities (nodes) within multiple countries (areas), where: The physical time it takes to travel...
What is the Difference between a Heuristic and an Algorithm? ...
Today I read that there is a software called WinCalibra (scroll a bit down) which can take a text file with properties as input. This program can then optimize the input properties based on the output values of your algorithm. See this paper or the user documentation for more information (see link above; sadly doc is a zipped exe). Do ...
This is for http://cssfingerprint.com I have a system (see about page on site for details) where: I need to output a ranked list, with confidences, of categories that match a particular feature vector the binary feature vectors are a list of site IDs & whether this session detected a hit feature vectors are, for a given categorization...
