Automated conjecture making in number theory using HR, Otter and Maple

Simon Colton
2005 Journal of symbolic computation  
We add some automation to this discovery process by using the HR theory formation system to make conjectures about Maple functions supplied by the user.  ...  We describe the core functionality of HR which enables it to form a theory, and the additional functionality implemented in order for HR to work with Maple functions.  ...  We would also like to thank the anonymous referees from the Calculemus conference for their interesting comments and suggestions about this work, and the organisers of that conference, at which this material  ...

On Euler's "Misleading Induction", Andrews' "Fix", and How to Fully Automate them [article]

Shalosh B. Ekhad, Doron Zeilberger
2013 arXiv   pre-print
Usually he had an uncanny intuition on how many "special cases" one needs before one can formulate a plausible conjecture, but one time he was "almost fooled", only to find out that his conjecture was  ...  But in order to turn the empirical proof into a full-fledged rigorous proof, we must make sure that we check sufficiently many (but still not that many!) special cases.  ...  Interlude: Even Giants make stupid conjectures We are a little surprised that Euler could have believed, even for a second, that Eq. (Leonhard) is true for all n.  ...

Explicit expressions for the moments of the size of an (n, dn-1)-core partition with distinct parts [article]

Anthony Zaleski
2017 arXiv   pre-print
We exhibit formulas for the moments of the size, as functions of d with n fixed, and vice versa. We conjecture that the distribution is asymptotically normal as n approaches infinity.  ...  In particular, we conjectured that the distribution is asymptotically normal.  ...  Then X d,n is a random variable, so it makes sense to inquire about its distribution.  ...
