{Over|More than} the {last|final} {few|couple of|handful of} decades enhanced sampling {methods|techniques|strategies|approaches|procedures|solutions} have {made|produced|created} {great|fantastic|excellent|wonderful|good|terrific} strides. {Here|Right here}, we exploit this progress and propose a modular workflow for blind reaction discovery and characterization of reaction paths. Central to our {strategy|technique|method|approach|tactic} {is the|will be the|may be the|would be the|could be the|is definitely the} use {of the|from the|in the|on the|with the|of your} {recently|lately|not too long ago} {developed|created} {explore|discover} variant {of the|from the|in the|on the|with the|of your} on-the-fly probability enhanced sampling {method|technique|approach|strategy|system|process}. Like metadynamics, this {method|technique|approach|strategy|system|process} is {based on|according to|depending on|determined by} the identification of {appropriate|suitable|proper|acceptable} collective variables.Our {first|initial|very first|1st|initially} step {is the|will be the|may be the|would be the|could be the|is definitely the} discovery of new chemical reactions and {it is|it’s|it really is|it truly is|it can be|it is actually} performed biasing a {one|1|a single|one particular} dimensional collective variable derived from spectral graph theory. {Once|As soon as|When|After} new reaction pathways are detected, we construct ad-hoc tailored neural-network {based|primarily based} collective variables {to improve|to enhance} sampling of {specific|particular|certain|distinct|precise} reactions and {finally|lastly|ultimately} we refine {the results|the outcomes} {using|utilizing|making use of|employing|working with|applying} {free|totally free|free of charge|cost-free|absolutely free|no cost} {energy|power} perturbation theory.

Our workflow {requires|demands|needs|calls for} minimal user input, and {thanks to|due to|because of} its modularity and flexibility, can extend the scope of ab initio molecular dynamics for the exploration and characterization of reaction space.
