One of the constraints evaluates to a FALSE LOGICAL variable. Your model is infeasible

[Yikxinxin]

Dear Johan, I encountered this error prompt while editing constraint conditions. May I know the reason? How can I solve this problem? Among them, delta (t)+p_ Fut (t) is a variable of type sdpvar.

Something evaluates to something like 1==0

sdpvar x
y = x+1
x >= y
Error using >=
Error using constraint
Inequality constraint evaluated to trivial false (no decision variable in constraint)

Also, the use of short-circuit && appears odd since it should not work

x>=1 && x<=2
The following error occurred converting from constraint to logical:
Conversion to logical from constraint is not possible.

as you must use &

x>=1 & x<=2
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
| ID| Constraint| Coefficient range|
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
| #1| Element-wise inequality 1x1| 1 to 1|
| #2| Element-wise inequality 1x1| 1 to 2|
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Better to not use & as it is confusing to most, better to just concatenate

actually, that must mean the stuff you have with p_Tra >= ... actually doesn't involve any sdpvars and evaluates to false

That's right, I got it.
