How to solve Time limit exceeded problem?

Question

Here is my program using bisection method
total_cost=1000000
S=float(150000)
G=1.07
down_payment=float(total_cost)*0.25
r=(1+0.04/12)
current_saving=0
low=0
high=1
x=(low+high)/2.0
eplison=100
months=0
while abs(current_saving-down_payment)>eplison:
while months <=36:
current_saving=current_saving*r
if months%6-1==0 and months>=6:
S=S*G
current_saving=current_saving+S*x/12.0
months+=1
if current_saving-down_payment>0 :
high=x
x=(low+high)/2.0
if current_saving-down_payment<0 :
low=x
x=(low+high)/2.0
print('Best portion for saving within 36months is',x)
print(current_saving)

Answer 1

Here you operate in a virtual environment which has its limitations. Too much overcalculation and your code goes bust :/

Answer 2

I checked your outer 'while' with:
print( abs( current_saving -
down_payment), eplison)
ctr+=1
if (ctr>15): break
The end conditions never change. It looks like it will run forever, anywhere.

Answer 3

Program it in a local machine, that way you have no time limit for a programs runtime.

Answer 4

That's server

Answer 5

Ok. I should run simplified program in this platform
