I am writing a program in C. I want to find a solution by minimizing expression
D1+D2+ +Dn
where Di's are distances calculated by distance formula between 2 points. The above expression is in x & y variables
Now I will differentiate this expression and...

At least one long distance, you've a good chance that the sum of squares has a different minimum are unrelated , then for each individual distance the square is minimal when the distance is and thus case isn't possible (AFAIK).

Modifying a Levenshtein distance function to calculate distance between two sets of x-y coordinates?
I've been trying to work on modifying a Levenshtein Distance function so that it can find the distance between two lines, or sets of x-y coordinates (in other words, how similar or different the lines are, not their geometric distance). I'm running into...
Answer Snippets (Read the full thread at stackoverflow):
Wouldn't it be more clever to use geometrics for calculating the distance between two lines of intersection, unless they are parallel (edit, thanks) , it's easy to calculate the smallest distance((x_1-x_2)/(y_1-y_2))) and subtract them.

Hi, now say someone is 10 miles away and you hear them transmitting, can you transmit back and that guy hears you.

Sounds like I got the concept but cant seems to get the implementation correct. eI have a cluster (an ArrayList) with multiple points, and I want to calculate avg distance. Ex: Points in cluster (A, B, C, D, E, F, ... , n), Distance A-B, Distance A-C,...
Answer Snippets (Read the full thread at stackoverflow):
You add all the distances += distance(bigCluster[i], bigCluster[j]); } } return totDistance / (bigCluster.length * (bigCluster.length - 1)) /....
For it to connect to), each time looping from curPoint to N, calculating each distance.

I have a unit vector, a distance and a coordinate and I would like to calculate the new coordinate given by adding the distance onto the coordinate in the given direction. How do I do this?

Answer Snippets (Read the full thread at stackoverflow):
V = V unit * distance V unit = (1/2 sqrt(3), 1/2) distance = 6 ==> V = (3 sqrt(3), ....
You can find the coordinate bij multiplying all coordinates with the distance.
If with a unit vector, you mean a vector with distance 1.

Hi to All,
I want to calculate the distance between 2 points in Google Maps. I have the latitude & longitude of both points but want the distance between them.

There you can, given any two lat/lng points, you can easily calculate to good accuracy the distance between those() function on the following page:

Is there a free plug-in for Adobe Reader to measure a distance on a PDF?
Is there another free reader out there that has this?

Distance_of_time_in_words is great, but sometimes it's not granular enough.
I need a function that will report exact distances of time in words. E.g., 7:50AM to 10:10AM should be a distance of "2 hours and 20 minutes", not "about 2 hours" or whatever ...

I'm trying to make a "better" distance_of_time_in_words for rails and so far I have this: http://github.com/radar/dotiw .
However, at the moment it chokes on months + years, as shown by the specs. I'm at a complete loss! Help?

From that you can calculate the distance by finding out what the angle from one point to the other is not a perfect sphere it gets a little ....
I guess you want it along the curvature.
This algorithm is known as the Great Circle distance .
