|
This run was started on 10/23/2020. The purpose was to attempt to demonstrate evolution by beginning from 50 identical individuals in the initial
generation (which had previously produced a low score).
This run was the first time we removed the penalty on fitness scores for antennas which exceeded the borehole radius. It was also the first time |

Tue Jun 7 12:20:23 2022, Alex M, Run Details: 2022_04_14_Identical_Asym_Lower_Min
|
This run was a short run (stopped due to resource limits) that was conducted to test the minimum length constraint that had been applied in the past.
Previously, the minimum length was set to be 37.5 cm for each cone; in this run, it was lowered to 10 cm. It ran for 60 generations with 50 individuals
per generation, each evaluated with 300,000 neutrinos. To compare to the paper run, this run was performed using the asymmetric algorithm, meaning each |

|
This is the run that is discussed in the GENETIS paper submitted to Physical Review D in December of 2021. It was conducted beginning on March 19, 2021.
The preprint can be found here. It ran for 31 generations with 50 individuals per generation. Each individual
was run through AraSim for 300,000 neutrinos. |

Tue Jun 7 11:01:59 2022, Alex M, Run Details: 2022_02_08_Rank_Test
|
This run was started on February 2, 2022. It is a full run of 50 generations with 50 individuals per generation using the quadratic version of the loop.
This means that each individual is defined by 8 genes (length, inner radius, linear coefficient, and quadratic coefficient for each cone). Attached is
the txt file run_details.txt that is automatically generated when the loop is run. Each individual was run for 300,000 neutrinos. |

|
This is a duplicate post of a previous post from the end of 2020 where I listed the important runs with some of their details in a table (as below).
I am extending this table to include the important runs that have been conducted since this post. This includes the run used for the paper as well as the
curved run done earlier this year. |

Fri Apr 8 16:07:22 2022, Alex M, Identical Asymmetric Lowered Length Minimum Run
|
We are trying to do a short run of the asymmetric bicone so that we can see how it tries to evolve the antenna when the minimum length is lowered from
37.5 cm to 10 cm. Currently, there is a problem with the loop in the asymmetric version. Attached is the run detail file. |

|
The reviewer for the paper we recently submitted mentioned that our step sizes at which we are measuring the gain in XFdtd may be too large. They pointed
out that there appear to be "lobes" at 400 MHz. I ran the antenna we presented in the paper through XFdtd using a step size of 5 degrees
(what we've been doing) and a step size of 1 degree (the reveiwer's recommendation). Attached are antenna responses for these two different step |

Fri Mar 25 17:14:01 2022, Alex M, Antenna Minimum Length Investigation
|
The reviewer of the paper we are trying to publish (as well as other external colleagues we showed the paper to) asked about our minimum length we implemented
in the loop. Currently, we cut off the length at a minimum of 37.5 cm for each cone (minimum of 75 cm for the full cone). There is an ELOG post from Amy
that presented the reasoning for this ( http://radiorm.physics.ohio-state.edu/elog/GENETIS/81 ). We initially thought that we needed a minimum because |

|
I fixed a bug in the loop, so we started another rank test run. Run details in the attached file.
The bug was searching for the generationDNA.csv file in the wrong place, meaning that it wasn't able to copy it to the run directory. That
meant we didn't have a record of the generation data in the usual format. I don't think that this explains the flatness, since the the generationDNA.csv |

The following plots are ittereations if the test loop that add increasing improvements to the GA.
The first plot shows the GA's behavoir unaltered from our previous runs (80% roulette, 20% tournament elite selection on).
The second plots shows when we use 90% rank selection and 10% tournament, elite selection off. |
