1. 1 Status Update September 17 th, 2014 Erik Fredericks

2. 2 Agenda Grammar update Output update Next steps

3. 3 Grammar Update Recursive composition added Tree could not figure out how to “find” multiple compositions with only top-level available for multiple compositions (i.e., sequential compositions) Statements reordered Statement, Module (opposed to Statement, Module, Statement) Attempt to move transforms outside of module invocation Fitness completely refactored “Harsh” penalties removed to allow more exploration

4. 4 Grammar Update Sometimes, converge to proper solution All roles matched All targets composed Sometimes will not converge however… Current grammar auto-generated EpochX format here: ftp://ftp.cse.msu.edu/pub/serg/BAE/resources/src/gra mmar/grammar.epochx.v8

5. 5 Output Update Converged to solution for single composition: SAGE_FUNCTION( COMPOSITION( EXPAND(public_sorted_values), MODULE( openssl_public_decrypt, EXPAND(ARR-FLOAT2INT(public_incoming_array)), CHAR2INT(DOUBLE2CHAR(private_convert_me_to_int)), FLOAT2INT(DOUBLE2FLOAT(public_convert_me_to_int)), public_sorted_values) )

6. 6 Next Steps Finalize addition BECS example i.e., actual encryption/decryption functions Decide how to perform experiments Replicates Comparisons Begin general writeup for tech. report Enable code generation
