Hello,

After coming this error i add SCS solver . But the same error is happening

[julia-users] Re: How to get the particular value from the table

[tannirind]

Thank you David,

Basically I want to solve a simple optimization problem for the cost of the 
grid. So I want to to to import the forecasting file(file.text) for the 
power consumption (p1,p2...p24) and the cost (c1,c2c24)of the energy 
for the 24hrs. Cost and power is different at every hour.

with this formula
@objective(m, Max, sum{p[i]*c[i], i=1:24})

Is this right approach ? or if you have any idea then please suggest me how 
can I handle this problem ?

[tannirind]

According to time interval (hours) I want to access different power values 

like sum{p[t]*c[t]}, t = 1:N

[julia-users] Given code is not giving the optimal solution .

[tannirind]

Hello to every one,

Any one can tell me the code given below is not giving the optimal solution 
.it gives the just range of x1 and x2. I want to calculate optimal value of 
the function. Thank you for your time.

Best Regards,
Tanveer Iqbal

using JuMP
using Ipopt
m = Model(solver = IpoptSolver())

@defVar(m, 0 <= x1 <=3)
@defVar(m, 0 <= x2 <=7)

@addNLConstraint(m, x1+2x2 <=8)
@addNLConstraint(m, 2x1 + x2 <= 10)
@addNLConstraint(m,  x2 <= 3)

@setNLObjective(m, Min, (x1)^2 +2(x2)^2 + 2(x1)+ 3(x2))

solve (m)

print(m)

I was trying with this code here "using JuMp" is already mentioned

[julia-users] To solve optimization problem in julia is it necessary to add any module.

For the solving of optimization problems in julia is it necessary to add

If it is necessary to add then which one is best ?

[julia-users] Re: I am Getting problem with julia and light table to work them together

[tannirind]

Yes Tomak,

When i write a code but it is not connected with julia in real time.Or even 
when I I press the key Shift+Enter it doesn't work also. suppose I wrote a 
simple code such as 
a=2
b=3
c=2+3
but pressing the key Shift+Enter it dont show the result on the julia.Can I 
fix this problem ? if i do not install any other text editor.
