5 Refine a problem by a search for a \<open>ML_structure Model_Pattern\<close>
6 better fitting the respective where_-condition.
8 The search on the tree given by @{term Know_Store.get_pbls} is costly such that
9 \<open>ML_structure Know_Store\<close> holds terms pre-parsed with a most generally type.
11 On transfer to a calculation these terms are strongly typed by Model_Pattern.adapt_to_type
12 (and users of this function in \<open>ML_structure Error_Pattern, MethodC, Problem\<close>)
13 according to the current context.
15 Note: From the children of eb89f586b0b2 onwards the old functions (\<open>term TermC.typ_a2real\<close> etc)
16 are adapted for "adapt_to_type on the fly" until further clarification.
