TPTP Combine Proof

  • a test case created by Geoff
  • cynthia produced combined proof
  • results
    • something unexpected
    • not meeting the anticipated proofs
  • 1. Stabilize current combingin software
  • 2. Add greedy hill-climbing algorithm
  • 3. Apply to Mizar proofs
  • 1 redundant proofs (which he and cynthia will work to refine)
  • 2 unexpected proofs (although with discussion it could be that those proofs may be redundant but they are still interesting since they may be evidence for promise of coming up with novel proofs that are truly new and better
  • 3 a clearly better proof as judged by any metric

uses a subset of the original fof axioms , subset of internal nodes, all metrics from paper at workshop

Wine Proof

we need to understand if Wine Agent proofs are good enough to generate explanations. Cynthia showed an example in IW browser, what explanation can be generated from wine agent proofs http://browser.inference-web.org/iwbrowser/NodeSetBrowser?w=900&mg=999&st=Dag&fm=English&url=http%3A%2F%2Finference-web.org%2Fproofs%2Fwino%2F40___owql_0%2F_owql_0ns1_0.owl%23_owql_0ns1_0

TODO: deb follow up with Cynthia on the potentials of this demo
