Hello,
Could you please help me with the modeling in Python the following
problem: (e.g., g_t means g with index t)
Min∑_(i=1)^n▒∑_(t=1)^l▒[s_i (t)-min[s ̂_i (t)×α_t×exp(g_t ),C_i
(t) ] ]^2
subject to
s_i (t)=f_i (t)[S_i+f_(i-1) (t)[S_(i-1)+f_(i-2) (t)[S_(i-2)+⋯f_2 (t)
[S_2+f_1 (t) S_1 ]…] ] ][1-
Here we need to estimate p_i, q_i, and β.
Thank you,

Dear Ulrich Eckhardt and Jean-Michel Pichavant!
First of all thank you for your attention. I'have never expected to
receive response.
Actually, I am doing my internship in Marketing Division in small
company., I got this assignment yesterday morning. My boss wants
