SLIDE 1

Improving KeYmaera

Less clicking, more proving

SLIDE 2

Motivation & Initial Idea

improve the user-KeYmaera experience
implement convenience features in

KeYmaera

reduce the amount of clicking

SLIDE 3

Changes from initial idea

moved over to KeYmaera 4
added text interface

SLIDE 4

Changes in KeYmaera 4

Client-server architecture
Web interface

SLIDE 5

An Example!

(A ∧ B ∧ B → C) → C

SLIDE 6

Example: Key File

Functions. R a. R b. R c. End. Problem. (a & b & (b -> c)) -> c End.

SLIDE 7

Example

An actual demonstration!

SLIDE 8

Implementation: Initial syntax

<formula id>/<tactic id>
ex: succ:0/dl.imply-right

SLIDE 9

Implementation: Less verbose

<formula id>:<tactic id>
ex: 1:imply

SLIDE 10

Implementation: Saturated tactics

Simple notation: add * to tactic name
ex: -1:and*

SLIDE 11

Implementation: Autocomplete

Three stages of suggestions
Formula name
Tactic name (full and short)
Saturated

SLIDE 12

Implementation: Multiple tactics

Separated by newlines or semicolons
Faster, but requires advanced knowledge
No autocompletion

SLIDE 13

Next steps

Allow multi-formula tactics (ex: axiom close)
Allow interactive tactics (ex: loop ind)

SLIDE 14

Summary

Added text-based interface
Has autocompletion
Ability to apply multiple tactics
