Use equivalence-classes for questions related to decomposing a set into subsets in which each element produces a constant output given a constant input
I have a Advanced Search feature where in I first search for a key word and then i refine my search by selecting the different filters in a different category, these are multi-select check boxes.
Example: Lets say I am looking for a "Car" once I…
What I have: an equivalence relation on the set {1,...,n}, given as the full list of equivalent pairs (a,b) (this is already transitive; no need to compute a transitive closure). n is large (say, a few millions at most); the total number of…
I need help with some 2 questions , thank for help
There will be L ⊆ Σ* , Prove or disprove:
1. If each RL equivalence class is a regular language, then RL contains an infinite equivalence class
2. If L is a regular language, then RL contains an…
Say I have points:
points = [(1., 1.), (3., 0.), (-1., -1.), (9., 2.), (-4., 2.) ]
If I sort them by y axis:
points = sorted(points , key=lambda k: [k[1], k[0]])
I get
points = [(-1., -1.), (3., 0.), (1.,1.) , (-4.,2.), (9., 2.)]
However I…
Suppose that I have two sets of items, and a function to check the equivalence of two items (not strict equality so that one item may be equivalent to multiple items in the other set), I want to determine whether there is a one-to-one correspondence…
I am using Protege 3.5 ontology editor. I have two classes "ProcessName" and "AvailableProcess". I would like to say that these two classes are equivalent, i.e. that they have the same class extension (same instances in both classes). I would use it…
I have a couple of proeblems which I am not sure how to solve. I know that an equivalence relation is a relation set that corresponds to the properties: reflexive, symmetric, anti-symmetric and transitive.
1) Consider the alphabet Σ = {a,b}. For…
The domain and range of owl:equivalentClass raises some questions to which I have been unable to locate the answers.
First of all, in OWL itself, the domain and range of owl:equivalentClass is set to rdfs:Class. This domain and range seem to clash…
Hey guy's i'm taking a software testing module and trying to study for the final coming up soon but having a little problem getting my head around some of it the question that was asked last year is
A large activist organisation uses an add-on to…
I have a problem that's proven to be dramatically more complex than it at first seemed. I have a (long) list of equivalence relations of the form e = abe. I need a function from string to string that produces the same output for any two equivalent…
Is it possible that a context-free-language has infinite myhill-nerode-classes or is there a way to narrow down (in terms of chomsky hierachy) which kind of classes can or can't have infinite myhill-nerode-classes?
I have a problem where I should…
The program uses vertices in R^2 as nodes and there are edges between nodes, and ultimately more is built from there. There are a high number of circuitous ways that a point (x,y) in R^2 might be reached that may rely on layer after layer of trig…
I have a set of pairs which represents equivalency among them:
[(“Player1”, “Player2”), (“Player3”, “Player4”), (“Player2”, “Player3”), (“Player11”, “Player13”)]
This means, “Player1” is equivalent to “Player2” and “Player3” is…
I have a method isPerfect(x) (with 4<=x<=10000) below, how to write test cases based on Equivalence Class, Boundary Value, and Basis Path Testing:
public boolean checkPerfectNumber(int x) {
if(x >= 4 && x <= 10000) {
int sum = 0;…
I have a csv file where each row contains a pair of values. For example, it might look something like this:
A, B
B, D
E, G
F, G
H, C
Each row should be interpreted to mean that the two values should be in the same group. I'm trying to find an…
