Hi Jasmin,
I finallly discover your paper "Machine Learning for Sledgehammer". So now
I know
what it means. I have only to discover how to disable it (within jEdit?).
Best!

Hi Jasmin,
That’s really bad — that lemma is supposed to be ultra easy. In a previous
email, I suggested > you try disabling MaSh. Did that make any change?
I certainly missed that remark. I have no idea what is MaSh. How can I
disable it?
There is something about it in Isabelle Plugin Options.
Best!

Makarius, please don’t release anything until then. ;)We’ll also see if we manage to reproduce the issues. I unfortunately have
no Windows license anymore now that I’ve left the TU München, so I need to
find a solution quick or rely on your remote debugging. If you think this
could be useful, we could try a chatting session. Otherwise, I could try
pestering my Windows-based students. ;)Cheers,

OK, that failed unfortunately. We got a 400 MB binary, which is definitely too big for Isabelle. Plan B...

Hi all,
It turns out that the solution was as simple as “strip”ping the file. Now we’re back at 14 MB.
I have prepared a new component and a corresponding change for “isabelle-release”. The binary comes from Mathias, but we haven’t tested the full loop yet.
Mathias, now that the component is ready, could you apply the following change to your Isabelle (e.g. using “qimport” and “qpush” or even just modifying the two files manually or with the “patch” program)? Then the acid test in Isabelle is something like
lemma “rev (rev xs) = xs”
sledgehammer [cvc4, debug]
Check that the minimizer starts with “Testing 1 fact”, not “Testing N facts” for some large N. If this works, please tell us so that Makarius can include the change to “isabelle-release”.
Makarius, if you are impatient, you can try out the change yourself and tell us how that went.
I’m sorry for the last-minute trouble with this. This won’t solve all the issues Alfio reported (I’ll come back to them later), but it will certainly give a boost to Sledgehammer on Windows.
Cheers,
Jasmin

Dear Isabelle users,
Isabelle2015-RC3 is now available for further testing:
http://isabelle.in.tum.de/website-Isabelle2015-RC3
Changes can be inspected formally here:
https://bitbucket.org/isabelle_project/isabelle-release/commits
This is an informal summary of notable points:
- misc tuning of Isabelle/jEdit
- updated and extended "jedit" manual (including new bibtex mode)
- improved 'lift_definition' command and update of "isar-ref" manual
- last-minute refinements of Eisbach
- further polishing of BNF datatype package
- further polishing of Sledgehammer
- Windows: workaround for cvc4 in Sledgehammer
- Ubuntu 15.04: avoid odd warnings about JAVA_TOOL_OPTIONS
With ever increasing size and complexity of the system and its many add-on
tools, it is important to take testing of release candidates seriously.
People who have tested earlier release candidates should upgrade now.
Local settings can be preserved by copying $ISABELLE_HOME_USER in a
suitable manner: renaming the last component of the directory name to
Isabelle2015-RC3 before starting the new version.
The main forum for discussion is here on isabelle-users, but it is also
possible to contact the person who is responsible for particular Isabelle
tools via private mail -- better than keeping potential problems private.
When reporting problems, the subject line should be changed to something
meaningful, such that the mailing list traffic becomes more manageable.

Dear Makarius and Jasmin,
I have just tried Sledgehammer with RC3 with the (now usual)
following lemmas (without using try methods):
lemma "[a] = [b] ⟹ a = b" oops
lemma aux: "m < n+1 ⟹setsum f {m..n + 1} = setsum f {m..n} + f (n + 1 ::
int)"
oops
Isabelle for Linux (installed in a virtual machine): Both lemmas
are solved very quickly. The second is solved with cvc4 and z3.
I launched s/h with the standard initial configuration.
Isabelle for Windows: Using the standard configuration, s/h
solves the first lemma only with e (and it takes quite some time
to do it). With the second lemma, all provers time out. Using
timeout=60 and Threads=1, the second lemma is solved with Z3
(after a considerable amount of time, if compared with the linux
version). Strangely enough, the first time I launched s/h, I got
a message in a terminal window stating that cvc4 binary file
was compiled without proof support (or something like that).
My machine (laptop) configuration:
Operating System: Windows 8.1, 64-bit operating system
Ram Memory: 8GB
Processor: intel i5-3230M, 64 bit processor
Best!

If this proves to be necessary, I'll be more than willing to help.
