Rules DEF_EXPN_STEP, SIMP_{MIN,MAX}_IN and SIMP_KBOOL_LIT_EQUAL_TRUE have been implemented in Rodin 3.9
 
(34 intermediate revisions by 6 users not shown)
Line 1: Line 1:
Rules that are marked with a <tt>*</tt> in the first column are implemented in the latest version of Rodin.
Rules without a <tt>*</tt> are planned to be implemented in future versions.
Other conventions used in these tables are described in [[The_Proving_Perspective_%28Rodin_User_Manual%29#Rewrite_Rules]].
