querying rdf triples
by orson in Coding

How can I write sparql query where I can compare the variables (?a, ?b), if I have the following eg? (something's wrong with this eg?):


<ont:XXXXX rdf:about="http://www.myOntDomain#C">
<ro:part_of rdf:resource="http://www.myOntDomain#A">
<ro:part_of rdf:resource="http://www.myOntDomain#B">
</ont:XXXXX>

How big is a billion triples?
by Tom Clark in Databases

Is it possible to relate the size of a triple store to a rough equivalence in terms of a RDBMS? Or would this vary too much based on the type of data stored (in my case text content of a CMS)


I'm trying to get my head round how a 800MB database compares to a 1.7Billion triple triple store. I'm fully prepared to be told this is a daft question.

All possible Pythagorean Triples
by SnuggleTheBear in Programming Languages

Here is the question


Find all Pythagorean Triples for side1, side2 and hypotenuse all no longer than 500. Use a triple nested for loops that tries possibilities.


The below is my attempt


#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
int side1 = 0;
int side2 = 0;
int rightS

finding pythagorean triples (a,b,c) with a <=200
by besn in Development Tools & Services

In my previous post on this subject i have made little progress (not blaming anyone except myself!) so i'll try to approach my problem statement differently.


how do i go about writing the algorithm to generate a list of primitive triples?


all i have to start with is:


a) the basic theorem: a^2 + b^2 = c^2


b) the fact that the small sid


How to Generate Pythagorean Triples
by danielsdesk in Education
According to the Pythagorean theorem, the square of the length of a right triangle's hypotenuse equals the squares of the two shorter lengths. The Pythagorean theorem can also be written as a^2 + b^2 = c^2. Sets of values that fulfill this theorem are called Pythagorean triples. For example, 3, 4 and 5 is a common Pythagorean triple; 3^2 + 4^2 = 5^2, because 9 + 16 = 25. You can generate sets of

pythagorean triples exercise
by Olympian Last in Development Tools & Services

i need a quick hint regarding the following exercise question:


Write a program that generates all Pythagorean triples whose small sides are no larger than n. Try it with n <= 200.


what is "no longer than n" all about ??


exercise source: Java by Dissection (Ira Pohl and Charlie McDowell)


note: i found what looks to be a very good post on pyth


AllegroGraph - UTF-8 characters in N-Triples
by Hosein Mohtasham in Programming Languages

When I use the AllegroGraph 4.6 Python API, I can use the connection.addTriple() method to try to add a triple that ends in a literal containing a unicode character (×):


conn.addTriple( ..., ..., '5 × 10**5' )


This doesn't work. I get the error:


UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position...

How to Solve Pythagorean Triples
by kiirpi in Education
A Pythagorean triple is a set of three positive integers that are solutions to the Pythagorean theorem. That theorem states that, in any right triangle (a triangle where one angle is 90 degrees), the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. It is often written as a^2 + b^2 = c^2.
To do this, first assume you have been given a and

Calculating pythagorean triples
by Anderson in Programming Languages

I was writing some code to calculate Pythagorean triples, but then I got some values which were not solutions. Here is the code:


#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int j, counter = 0;
double candidate, sqrnbr;
for (int i = 400; i <= 500; i++) //note that the range is only from 400-500 since I a

Rules for Tennis Triples
by Rit Li in Sports & Fitness
Tennis triples, a unique tennis game, is an alternative to playing singles or doubles. Many of the rules are the same as in singles or doubles with a few minor changes. There are six players, compared to two or four, making it a very social game. Playing triples may be a little confusing at first and a little crowded. After a few games, however, you will soon learn the subtleties and quickly maste
