Worked with Alex to change the roulette algorithm to implement a cut on the minimum length for the Antennas. Amy showed that we don't want to generate antennas which are shorter than 37.5 cm in length (for each cone, so a total of 75 cm all together) because anything shorter than that won't be reliably simulated in XF for our frequency range. To do this, we made the roulette algorithm reselect individuals in the 0th generation if they were below this length. When it's making new individuals for the next generation, we made it so that the algorithm doesn't apply mutations that would make the antenna smaller than the minimum length (but we may revisit this with other methods, like letting the individual die if its below that length).

Spoke to Ben about AREA. He can run it, but there are some errors, and it looks like the job was killed when we tried submitting it to the queue. We'll have to see if we can track down some of the errors.

Alex and I will try to run the loop using our changes to the roulette algorithm and see what the new individuals look like and if the effective volumes are reasonable.
Alex P Worked on converting the c++ programs I made for database to work with a variable amount of genes rather than just LRT. After that Amy met with Alex and me and discussed the proper length to limit the antennas to and then worked with Alex to put a clamp within the roulette algorithm on both the initial generation and the generation of lengths through mutation. Then deciding to just cut the individuals that have too low lengths and discussing how that would be implemented. Will continue to implement and test the changes to clamping the length by eliminating low length individuals and once that is sorted start working on being able to make our changes work on other branches too so we can start to merge.
