Let's suppose at noon we run the algorithm, we first calculate the distance from each googler to one another:

int maxDist = range; // max limit for lunch together

distance[n][n] // store all distances - init with Int.MAX_VAL
persons // array of Persons object Person {id , coords}
for (Person p : persons ) {
for (Person j : persons ) {
if ( != && distance[][] != int.MAX_VALUE) {
distance[][] = calculateDistance(p.coords, j.coords) // apply formula based on coordinates
if (distance[][] >= maxDist) return false // no lunch possible
return true;
