             abstract = "Lighting intentions are the goals and constraints that designers 
                         like to achieve in a lighting design process. In this context, 
                         rendering problems are the kind of problems based on the rendering 
                         equation that are proposed to satisfy a set of lighting 
                         intentions. These problems are usually expressed as optimization 
                         problems. In this article is presented a novel method based on 
                         photon tracing, the VNS optimization metaheuristic, and the 
                         determination of the number of photons needed, allows to handle a 
                         wider variety of lighting intentions without incurring in high 
                         computational costs. Moreover, the method developed shows to be 
                         efficient when the geometry is also a variable in the rendering 
                         problem. The techniques explained here could be included in a 
                         package used by architects or designers to aid in the lighting 
                         design process of architectural environments.",
