    Simple evaluator for cost function


    Leonardo de Moura (leonardo) 2008-06-14.

Revision History:



class cost_evaluator {
    ast_manager &   m_manager;
    arith_util      m_util;
    unsigned        m_num_args;
    float const *   m_args;
    float eval(expr * f) const;
    cost_evaluator(ast_manager & m);
       I'm using the same standard used in quantifier instantiation.
       (VAR 0) is stored in the last position of the array.
       (VAR (num_args - 1)) is stored in the first position of the array.
    float operator()(expr * f, unsigned num_args, float const * args);

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
