The HP model for protein structure prediction abstracts the fact that hydrophobicity is a dominant force in the protein folding process. This challenging combinatorial optimization problem has been widely addressed through metaheuristics. The evaluation function is a key component for the success of metaheuristics; the poor discrimination of the conventional evaluation function of the HP model has motivated the proposal of alternative formulations for this component. This comparative analysis inquires into the effectiveness of seven different evaluation functions for the HP model. The degree of discrimination provided by each of the studied functions, their capability to preserve a rank ordering among potential solutions which is consistent with the original objective of the HP model, as well as their effect on the performance of local search methods are analyzed. The obtained results indicate that studying alternative evaluation schemes for the HP model represents a highly valuable direction which merits more attention.

BACKGROUND Liver transplantation for the most critically ill remains controversial;however,it is currently the only curative treatment *** To assess immediate posttransplant outcomes and compare the short(1 year)and long-term(6 years)posttransplant survival among cirrhotic patients stratified by disease *** We included cirrhotic patients undergoing liver transplantation between 2015 and 2019 and categorized them into compensated cirrhosis(CC),decompensated cirrhosis(DC),and acute-on-chronic liver failure(ACLF).ACLF was further divided into severity *** primary outcomes of interest were total days of intensive care unit(ICU)and hospital stay,development of complications and posttransplant survival at 1 and 6 *** 235 patients underwent liver transplantation(CC=11,DC=129 and ACLF=95).Patients with ACLF had a significantly longer hospital stay[8.0(6.0-13.0)vs CC,6.0(3.0-7.0),and DC 7.0(4.5-10.0);P=0.01]and developed more infection-related complications[47(49.5%),vs CC,1(9.1%)and DC,38(29.5%);P<0.01].Posttransplant survival at 1-and 6-years was similar among groups(P=0.60 and P=0.90,respectively).ACLF patients stratified according to ACLF grade[ACLF-1 n=40(42.1%),ACLF-2 n=33(34.7%)and ACLF-3 n=22(23.2%)],had similar ICU and hospital stay length(P=0.68,P=0.54),as well as comparable frequencies of overall and infectious posttransplant complications(P=0.58,P=0.80).There was no survival difference between ACLF grades at 1 year and 6 years(P=0.40 and P=0.15).CONCLUSION Patients may benefit from liver transplantation regardless of the cirrhosis *** patients have a longer hospital stay and frequency of infectious complications;however,excellent,and comparable 1 and 6-year survival rates support their enlisting and transplantation including those with ACLF-3.
