<result> <bug_free_depth> <engine_name> <0-based_output_num> <0-based_frame>
<INIT_STATE> : default is empty line.
<TRACE> : default is empty line
<result> is one of the following: "snl_SAT", "snl_UNSAT", "snl_UNK", "snl_ABORT".
<bug_free_depth> is the number of timeframes exhaustively explored without counter-examples
<0-based_output_num> only need to be given if the problem is SAT.
<0-based_frame> only need to be given if the problem is SAT and <0-based_frame> is different from <bug_free_depth>.
<INIT_STATE> : initial state
<TRACE> : input vector
<INIT_STATE>and <TRACE> are strings of 0/1/- ( - means don't care). The length is equivalent to #input*#<cyc>.
