Scipy optimise minimize
You can do a variable transformation, for example,
y[1]=x[1]
y[2] = x[2]-x[1]
y[3] = x[3]-x[2]
y[4] = x[4]-x[3]
Then you can use constraints like y[2] > 0, y[3] > 0, etc.
I am trying to solve the optimization problem with 4 variables.
I have to give constraint in the scipy.optimize,
the constraint is x[1] < x[2] < x[3] < x[4].
Is there any methodology to solve this problem in scipy.optimise
