PART A

3. You and your friend wish to meet for coffee. Your goal is to agree on a
location to meet. Your positions at time t are denoted by x1(t) and x2(t),
and are real valued. Both of you do not have a GPS device and can only
measure the relative distance between each other.
(a)
equation
Construct two functions (or strategies) R1 (y) and R2(y) such that for the differential
dx1
= R1 (x1 – x2)
(3)
dt
dx2
R2 (x1 – x2)
(4)
dt
we get lim,→0 |¤1(t) – x2(t)| = 0, irrespective of your initial positions x1(0) and x2(0).
Note: R1(y) and R2(y) should not depend on your initial positions (because you don't have
GPS). Additionally, note that the right hand-side in Equation (3) means we are evaluating
R1 (y) at y = x1 – x2 and similarly, we are evaulating R2(y) at y = x1 – x2.
(b)
tancing and maintain p units distance at equilibrium. Modify your functions R1(y) and R2 (y)
so that lim;→0 |x1(t) – x2(t)| = p, irrespective of your initial positions x1 (0) and x2(0). As in
part a), R1(y) and R2(y) should not depend on your initial positions.
Consider the alternative scenario that you and your friend must practice social dis-
