-# MOpt(imized) AFL by <puppet@zju.edu.cn>
-
-### 1. Description
-MOpt-AFL is a AFL-based fuzzer that utilizes a customized Particle Swarm
-Optimization (PSO) algorithm to find the optimal selection probability
-distribution of operators with respect to fuzzing effectiveness.
-More details can be found in the technical report.
-
-### 2. Cite Information
-Chenyang Lyu, Shouling Ji, Chao Zhang, Yuwei Li, Wei-Han Lee, Yu Song and
-Raheem Beyah, MOPT: Optimized Mutation Scheduling for Fuzzers,
-USENIX Security 2019. 
-
-### 3. Seed Sets
-We open source all the seed sets used in the paper 
-"MOPT: Optimized Mutation Scheduling for Fuzzers".
-
-### 4. Experiment Results
-The experiment results can be found in 
-https://drive.google.com/drive/folders/184GOzkZGls1H2NuLuUfSp9gfqp1E2-lL?usp=sharing.
-We only open source the crash files since the space is limited. 
-
-### 5. Technical Report
-MOpt_TechReport.pdf is the technical report of the paper 
-"MOPT: Optimized Mutation Scheduling for Fuzzers", which contains more deatails.
-
-### 6. Parameter Introduction
-Most important, you must add the parameter `-L` (e.g., `-L 0`) to launch the
-MOpt scheme. 
-
-Option '-L' controls the time to move on to the pacemaker fuzzing mode.
-'-L t': when MOpt-AFL finishes the mutation of one input, if it has not
-discovered any new unique crash or path for more than t minutes, MOpt-AFL will
-enter the pacemaker fuzzing mode. 
-
-Setting 0 will enter the pacemaker fuzzing mode at first, which is
-recommended in a short time-scale evaluation. 
-
-Setting -1 will enable both pacemaker mode and normal aflmutation fuzzing in
-parallel.
-
-Other important parameters can be found in afl-fuzz.c, for instance, 
-
-'swarm_num': the number of the PSO swarms used in the fuzzing process.
-'period_pilot': how many times MOpt-AFL will execute the target program
-	in the pilot fuzzing module, then it will enter the core fuzzing module.
-'period_core': how many times MOpt-AFL will execute the target program in the
-	core fuzzing module, then it will enter the PSO updating module.
-'limit_time_bound': control how many interesting test cases need to be found
-	before MOpt-AFL quits the pacemaker fuzzing mode and reuses the deterministic stage.
-	0 < 'limit_time_bound' < 1, MOpt-AFL-tmp.
-	'limit_time_bound' >= 1, MOpt-AFL-ever.
-
-Have fun with MOpt in AFL!
