Undirected Training of Run Transferable Libraries
TLDR
A problem that can deceive the system into converging to a sub-optimal set of functions is introduced, and it is demonstrated that a much simpler, truly evolutionary, update strategy doesn't suffer from this problem, and exhibits far better optimization properties than the original strategy.
A Simple Powerful Constraint for Genetic Programming
TLDR
This paper demonstrates the ability of Hereditary Repulsion to perform well on a range of diverse problem domains and traces the source of this high quality performance to a pleasingly simple constraint at the heart of the HR algorithm.
Manipulation of Convergence in Evolutionary Systems
Exploiting the path of least resistance in evolution
TLDR
This work examines the behaviour of HR on the difficult Parity 5 problem using a population size of only 24 individuals and dramatically improves the consistency of the algorithm, resulting in a 70% success rate with the same small population.
Seeding methods for run transferable libraries
TLDR
This work investigates mechanisms by which the library can be seeded with domain-specific functionality, rather than from a set of standard GP functions.
[Seeding Methods for Run Transferable Libraries] Capturing Domain Relevant Functionality through Schematic Manipulation for Genetic Programming
TLDR
This paper applies a recently developed technique of expression structure analysis and parametric distribution to the generation of functional content relevant to the problem domain, and introduces a new algorithm for adapting the schematic templates discovered by such an analysis into a family of related functional expressions.
AB032. SOH21AS152. Severity of presentations and surgical outcomes of patients undergoing laparoscopic appendicectomy during COVID-19
TLDR
This sub-analysis focused on patients that underwent laparoscopic appendicectomies for acute appendicitis and did not show an increased severity and change in surgical outcomes, but further analysis into the data on all procedures or an increased time period could demonstrate statistical significance.
AB137. SOH21AS049. Audit to evaluate the use of the tumour marker CEA in a level 3 hospital
SP2.2.13Audit to evaluate the use of tumor marker CEA in a level 3 hospital
TLDR
The tumour marker CEA is not useful as the initial work up of nonspecific complaints and its main use is surveillance after curative resection and for monitoring treatment for patients with advanced colorectal cancer.
