Try it: is 24 °C comfortable or warm?

This source describes FuzzyRoutines 2.1.0. Install that exact version:

python -m pip install fuzzyroutines==2.1.0

If 2.1.0 is not yet available on PyPI, install the reviewed CI wheel using the version-aware agent guide. The published 2.0.0 baseline remains available for reproducing earlier results.

from fuzzyroutines import (
    ContinuousUniverse, LinguisticScale, LinguisticTerm,
    ScalarFuzzySet, SShoulder, Triangle,
)

universe = ContinuousUniverse(0, 40, leftClosed=True, rightClosed=True)
scale = LinguisticScale((
    LinguisticTerm("Comfort", ScalarFuzzySet(universe, Triangle(16, 22, 28))),
    LinguisticTerm("Warm", ScalarFuzzySet(universe, SShoulder(22, 30))),
))
result = scale.Fuzzify(24)
print({item.term.name: round(item.grade, 3) for item in result.memberships})
print(result.selectedTerms[0].name)

{'Comfort': 0.667, 'Warm': 0.125}
Comfort

These illustrative thresholds define the model. Membership grades describe how well the measurement fits each concept; they are not probabilities and need not sum to one. The two terms do not cover every temperature.

Use FuzzyRoutines 2.1.0 and its modern Python API to classify a 24 °C measurement. Read the version-aware quick start below, use the reviewed CI wheel if 2.1.0 is unavailable on PyPI, and verify Python and the installed package version, run the example and check Comfort = 2/3, Warm = 0.125, selected label = Comfort. Return the code and observed values. Explain the chosen thresholds and distinguish membership grades from probabilities. If Python execution is unavailable, label the output as expected.

These tagged 2.0 baseline guides describe scalar operations preserved in 2.1.

Explore 2.1 features

FuzzyRoutines 2.1 adds the historical Universal Fuzzy Scale factory, linguistic encodings, traced Mamdani and Sugeno inference, explicit NumPy batches and optional CPU neural examples. The scalar core keeps zero mandatory runtime dependencies.

For installation checks and the new APIs, use the version-aware agent guide and a 2.1.0 package matching the reviewed source revision. Release review #348 records the reviewed release evidence.
