Dear all
Is it possible to specify length of bool list of the existential quantifier.
I have following proof
* (?FA FB FC.*
* mux_list_imp (TL (num_BV_f (SUC (LENGTH y)) (BV_n (not_0 a) + 1)))
a** F FA /\*
* mux_list_imp (TL (num_BV_f (SUC (LENGTH y)) (BV_n (not_0 b) + 1)))
b**

Hello everyone,
Professor Philippa Gardner (Imperial College London) is organising a
Royal Society Meeting on `Verified Trustworthy Software Systems’ on
4th-5th April with Mike Gordon (Cambridge), Greg Morrisett
(Harvard—>Cornell), Peter O’Hearn (Facebook) and Fred Schneider
(Cornell), and an
Hello everyone,
We are seeking two outstanding postdocs (one theoretical, one more
practical) with strong interests in the formal specification and
verification of concurrent and distributed systems to join the Program
Specification and Verification Group, led by Professor Philippa
Gardner, at
It might be easier to avoid using TAKE_DROP_LENGTH
but instead try to simplify your subgoal using
LENGTH_TAKE_EQ and LENGTH_DROP
Then I think you'll have to instantiate your subgoal 0 once with p,q
and once with q,p
Cheers,
Jeremy

Hey,guys
I am learning to use HOL4. Here are some questions about my proving:
g`!p q:bool list l:num list. (LENGTH p = LENGTH q) ==> (LENGTH (cx l p q) =
LENGTH p) `;
e (Induct_on `l`);
e (RW_TAC list_ss [cx_defn]);
- e (RW_TAC list_ss [cx_defn]);
OK..
