No boolean comparison

No boolean comparison

Description

Boolean values should not be compared to the constants TRUE or FALSE.

Rationale

This enforces compliance with a specific modeling standard by avoiding redundant expressions involving booleans.

The intent is to improve model conciseness: boolean variables should be used directly instead of being compared with TRUE or FALSE.

Verification

This rule checks all comparison expressions throughout the model (predefined operators =, <>, <, <=, >, >=). For each comparison, it recursively determines whether any side of the comparison resolves to a boolean constant, and fails if it finds one.

Resolution

Modify the offending flow to remove the comparison to a constant, and use the boolean value directly.
