hi

how are you ?

Please how can I formulate and code to optimize the following: 

 

 

M₁+M₂+M₃=5E+06x^-0.682

M=f(P_j,I_k)

J=1,……, n

k=1,……, n

 

For M₁, P₁=0.7-0.9     

For M₂, P₂=0.3-0.7

For M₃,P₃=0.5-0.7

 

For M₁ , I₁=0.7-1

For M₂, I₂=0.1-0.5

For M₃,I₃=0.3-0.7

 

M₁=[4670330-188888889]

M₂=[4670330-188888889]

M₃=[4670330-188888889]

  Hi Ziyad,

  You should have a look at our Modelling with Python webinar and our Python examples.

  You can model the term \(x^{-0.682}\) using the addGenConstrPow function.

  Depending on what your function \(f\) is, you might want to have a look at the other nonlinear functions.

  Best regards,
  Jaromił
