In Eureqa, I am getting solutions with a term "- *AE*Vsw", where "AE" and "Vsw" are variable names. What does "-*AE" mean? It doesn't seem to be the same as "- AE*Vsw" omitting "*", because the formula does not give reasonable agreement to the model in that case.
Hey @redenton, had a look into your question. Not sure if it is a visual bug but here for instance is a Eureqa formula like yours:
Here is the same formula displayed from the model logs:
There is now a number between the minus and asterisk.
Model Logs can be found here under 'log':
Not sure why its not displayed in the UI.
Great find! I agree that this looks like a visual bug - you may be able to see the correct expression by changing the rounding from 2 decimals to all (above the pareto chart). However, could you please send an email to firstname.lastname@example.org to create a ticket? Provide all the information you shared here too. If you'd prefer, I can create the ticket - just let me know.
@IraWatt @JessLin Jess, I can create a support ticket for this. Ira's hint to look at the log was very helpful. I didn't know you could find the solutions there. Thank you Ira! Based on the log, the term in question should have been "-4.09020687809093e-7*AE*Vsw" instead of "-*AE*Vsw". Showing all digits did not fix the visual display when showing "Eureqa Solutions". Perhaps this means there is a problem in displaying a number if it is too small, like here with the e-7 notation.
@redenton Great to hear the logs were the answer. Just a note that the equation in my log was different from the Eureqa equation shown (don't know if this is also a bug), I found the correct term in the Eureqa export. I also suspect it could be because its a small number : D.
