I think I have the answer, can you escrow the funds? Also do you think you can extend the date a few more days?

Edit: Nevermind, I'll just post the answers. Only for part a)

alpha = (mu)/[(mu+L)(mu+3L)]
xi = 3L/u
c = (s_k)(u+L)(u+L)(u+3L)(u+3L)/3L
k = (1/[(s_k)/m-(1+1/xi)*c*alpha*alpha*2*L)] + (mu+L)/[2*alpha*mu*L]

If it is correct, please send the BTC to this address: 13MLwx49jT4a2SSwD17qu1uaG1sbGMdrzi

Checking the solution!

Am I correct that you are suggesting the following?

k=1

alpha=(u + L)/2uL

e =4uL - 1

c=(sk/m - 1)/(1 + 1/(4uL - 1))*2u²L/(u + L)²

EDIT: I still need to check it, but I don't think it will work, since your first three lines contain a mistake...
1/k - 2alpha*u*L/(u + L) <=0;
1/k <= 2alpha*uL/(u + L);
k<=(u + L)/2alpha*uL

EDIT2: This solution does not work, since for u = 1, L =2, the second (original) equation does not hold.
(1+4*1*2-1)*(3)/(2*1*2) - 2/(1+2) = 5.3333... which is not <=0

I just checked and noticed I substituted a wrong value for alpha and so the result is incorrect. I can see that another memebr has tried solving the equation and if by chance his solution too is incorrect, I can try again.  Smiley

you can use Mathematica to solve this problem, it's not hard.

TriggerX,

Let u=1/100, L=2/100, s=1, m=2

Then xi = 6, c = 147/2000000, a = 100/21.

In that case the first three inequalities hold, but the last one doesn't.

BOUNTY STILL OPEN!!!!!

EDIT: I will pay $20 for EITHER a) or b) !!!! Will extend the deadline 24 hours from now.

xi = 2L/mu
alpha = 1/(1+xi)(mu+L)
c = (s_k)/(2*xi*mu*m*alpha*alpha)
k=(1/[(s_k)/m-(1+1/xi)*c*alpha*alpha*2*L)] + (mu+L)/[2*alpha*mu*L]

Is this correct?

I am not Math genius, but in high school we were told that if we had 5 variables and 4 equations for it, then it wouldn't be unsolvable . Wouldn't that be true for this case ?

TriggerX did not request an escrow. I'm checking his solution at this moment. If it's good, I'll send the money.

It took 30 minutes to figure it out and I don't want to type it all out again haha. If I have time I may post it here again.

As for the BTC, I have received it, thanks.
