“…Detecting potentially habitable exoplanets using machine learning tools have gained momentum in recent times (Bora et al 2016;Saha et al 2018;Basak et al 2020). This research suggests that the habitability can be viewed as probabilistic measure (Bora et al 2016), and such approaches require optimization and classification methods.…”

“…Bora et al ( 2016) introduced a Cobb-Douglas Habitability Score -a metric based on Cobb-Douglas habitability production function (CD-HPF), which computes the habitability score by using measured and estimated planetary parameters. Basak et al (2020) extended the CDHS model and proposed another quantitative metric for habitability -CEESA, which considers orbital eccentricity in addition to the same features used by the CDHS. These metrics, based on optimization methods, use only four physical planetary parameters (mass, density, radius and surface temperature), while there may be a need to accommodate more features such as, for ex., eccentricity, or orbital separation.…”

“…Since these eccentricity values are not beyond reasonable values, such models (CDHS) are therefore not tenable for accommodating the eccentricity parameter. To mitigate this problem, our group developed a new habitability metric, the Constant Elasticity Earth Similarity Approach (CEESA) [68]. The proposed metric incorporates eccentricity as one of the component features for estimation of the potential habitability of extrasolar planets.…”

“…A relationship between the two habitability metrics, CEESA and CDHS, was derived in [68]. The general form of the Constant Elasticity of Substitution (CES) production function [69] for two inputs (say, radius R and density D) is…”

“…In the last five years more studies have continued developing new indexes such as the Mars Similarity Index, MSI, focused on identifying planets that might be habitable but under extreme conditions of life ; , the Cobb-Douglas Habitability Score (CDHS) based on a production function and physical parameters such as radio, density, escape velocity and surface temperature (Bora et al, 2016) which has been recently recomputed (Basak et al, 2020) with the imputed eccentricity values by the 'Constant Elasticity Earth Similarity Approach (CEESA), or the Statistical-likelihood Exo-Planetary Habitability Index (SEPHI) which applies likelihood functions to estimate the habitability potential using seven inputs of both planets and their stars and condensing all this information in four sub-indexes (Rodríguez-Mozos & Moya, 2017). In this work, the selected inputs are related to the main physical information the planetary discovery projects provided.…”
