I have one question: does OpenFHE support (\>= or \<=) comparison range operations for continuous polynomial functions on real numbers? If yes, what algorithms scheme works for this? Thank you

OpenFHE does not currently provide the range functionality as a built-in feature. One could theoretically implement this in OpenFHE using FHEW/TFHE-based comparison but this feature is not readily available.
