Re-running the computation with changes to the input voltage variation will affect the output. In the output shown here, the voltage variation was input at 5 mV/°C which is much lower than the 25 mV/°C input in the preceding run. The voltage variation change resulted in the computation choosing a linear PTC as the best fit instead of an NTC. It can also be noted that one of the fixed resistors is non-existent in this case. That’s because the tool provides the fixed resistors only when necessary.
