For an exclusion switch involving FMN and MS2, reward designs that include some of the MS2 binding arm in at least one on the closing stems on the FMN aptamer loop. Give higher reward for more bases used, up to 5.

Dear jandersonlee,  
&nbsp;  
Your strategy has been added to our implementation queue and we should have it completed within the next two to three weeks. You can check the status of the implementation [here](https://github.com/vineetsk1/Switch-Strategies/issues/31).

We will also be uploading the code used to write your strategy on this [page](https://github.com/vineetsk1/Switch-Strategies) if you are interested in reading it later.

After implementing your idea, we will post the direct link to the code here. Then, we will then optimize the parameters, and test it. At that point, we will tell you the correlation of how good your strategy was and what the new optimized parameters are.

Thanks for sharing your idea!

Dear jandersonlee,

I am pleased to announce that a preliminary version of your strategy has been implemented with 31 lines of code. The code might slightly change in the future to remove bugs, but you can check the current version [here](https://github.com/vineetsk1/Switch-Strategies/blob/master/jandersonlee_use_MS2_arm_bases_in_closing_stem_for_FMN_aptamer.py). We will soon work on optimizing your parameters and testing the strategy.

Thank you again for sharing your switch strategy!
