Re: [Hol-info] rigorous axiomatic geometry proof in HOL Light

2012-06-06 Thread Bill Richter
John, I realized my miz3 Hilbert axiom formalization may not have been rigorous, or captured Hilbert's axiom, as I had no notion of line other than the datatype new_type_abbrev("line",`:point->bool`);; saying a line is a subset of our model of Hilbert's axiom. That's possibly buggy, because there

Tom Ridge and I formed two teams of one each using HOL4 and ProofPower-HOL (respectively) in the first VSTTE competition which was a slightly smaller scale affair at the previous VSTTE (it was a rather open-ended 2 hours during the conference rather than 48 hours strictly timed several weeks bef

Note that Datatype.build_tyinfos is only guaranteed to work on types that Hol_datatype produces. Does your datatype have some other features? In any case, what happens with gen_datatype_info? Thanks, Konrad. On Wed, Jun 6, 2012 at 12:33 PM, Ramana Kumar wrote: > Dear Konrad, > Thanks a lot for
