Enhancing Evolutionary Computation: Optimizing Phylogeny-Informed Fitness Estimation Through Strategic Modifications
Get PDFIn evolutionary computation, programs are developed using evolution\u27s basic principles, such as selection, mutation, and recombination, to iteratively improve problem solutions towards optimal outcomes in a reasonable amount of time. To save time and be more efficient, we are currently exploring a modified version of phylogeny-informed fitness estimation. The original version evaluates each individual program on a subset of the training cases and estimates the performance everywhere else according to its parent\u27s performance. Our approach involves comprehensive evaluation of promising programs across all training cases, increasing computational investment where the sub-sampled results indicated potential gains. This method led to our modified algorithms finding solutions in fewer generations, but at the cost of increased computation time. One question is how to determine whether a solution is promising enough to warrant this additional evaluation. To address this, we used a threshold-k, requiring that a child should be better than its parent in at least k training cases. Analysis of 30 trials on a simple test problem showed threshold-3 enhanced time efficiency, while threshold-1 minimized the number of generations needed for success. A further 100-run analysis with much lower generation limits revealed that threshold-1 secured the highest success rates. To sum up, we did a lot of interesting experiments using a modified version of phylogeny-informed fitness estimation, including comparisons between modified version and original one, 30 runs and 100 runs, complex regression problem and fuel-cost problem.https://digitalcommons.morris.umn.edu/urs_2024/1000/thumbnail.jp

Creative Project: Hydro Flask Advertisement and Marketing
Get PDF*Disclaimer: This is a student paper discussing marketing and uses an authentic brand as an example, but is not authorized by or associated with HydroFlask*
For this project, O\u27Leary chose to create an ad for the brand Hydro Flask. They are a water bottle company with a mission to reduce the use of one-time plastics, specifically plastic bottles. In this paper, O\u27Leary explains the different aspects of the Hydro Flask business, such as their reasons to believe, the kinds of companies they partner with, and the materials they utilize to create their products. She also discuss the reasons why her two ads appeal to two different audiences as well as why she put in the certain information she did in each one. Additionally, she discusses the target audience for her ads, an interview is provided of a past Hydro Flask customer, and she relays the future goals and objectives that the company should look into
