[Couenne] Regarding NEOS server and my optimization problem..

[Imtiaz Ahmed]

Hi,

I was trying to optimize the following optimization problem through NEOS
server using Couenne:

 

var d1;

var d2;

var s1;

var s2;

var r1;

var r2;

maximize Profit: d1*r1 + d2*r2;

subject to One: (1-d1)*((2^s1) - 1)/1 <= 1;

subject to Two: (1-d1)*((2^s1) - 1)/1 + (1-d2)*((2^s2) - 1)/0.5 <= 1.5;

subject to Three: (d1)*((2^r1) - 1)/1 <= 1;

subject to Four: (d1)*((2^r1) - 1)/1 + (d2)*((2^r2) - 1)/0.5 <= 1.5;

subject to Five: (1-d1)*s1 - d1*r1 >= 0;

subject to Six: (1-d1)*s1 + (1-d2)*s2 - d1*r1 - d2*r2 >= 0;

subject to Seven: d1>=0;

subject to Eight: d2>=0;

subject to Nine: d1<=1;

subject to Ten: d2<=1;

subject to Eleven: s1>=0;

subject to Twelve: s2>=0;

subject to Thirteen: r1>=0;

subject to Forteen: r2>=0;

 

Unfortunately, I don't find the result and get something message as below:

Time limit reached. Process killed

 

I was just trying to see if my problem can be solved by Couenne before I
install Couenne.

Would you kindly let me know how I should resolve the error?

Thank you,

Best,

 

Imtiaz
