Anyone know about any freely available software or code that can optimise protocol sequences for 3D unconventional electrodes setups, including borehole electrodes?
The closest research I found is the BGS optimised algorithm series (led by Paul Wilkinson) but I don´t think they are freely available - at least I couldn't find it anywhere.
I am also familiar with Electre Pro but it is neither free nor an optimisation framework.
I also know the SEER spreadsheet, but it is 2D, and very rigid in several aspects (electrodes spacing, arrays and total number of electrodes). It also does not allow exporting the protocol assessed.
Thanks.
Hi Bruna,
I had the same question a few years ago.
I emailed Paul Wilkinson at the BGS (as suggested by Thomas Hermans).
He directed me towards the following papers.
I applied the methodology presented in the papers and I wrote a Matlab Code available on Github (the comments are in French). You can find the published work here :
