— “Artelys Knitro and AMPL performance enables the automation of radiation therapy cancer treatment, resulting in faster treatment delivery and more accurate tumor irradiation and healthy tissue sparing. Thanks to the resolution of complex large scale optimization models more than 800 patients were treated since the beginning of the project.”
— “The use of robust, innovative and powerful components enables us to carry out reliable analyses about sensitive issues such as network security.”
— “Our software incorporates Knitro to solve very complex mixed integer nonlinear programming (MINLP) optimization problems. These problems must be solved in near-real time (at the 5 minute level), and we have found no other solver that matches the speed and accuracy of Knitro. In addition, the customer support at Artelys has been fantastic. They have been very responsive to our needs, have worked closely with us in product development, and have been very flexible in product implementation and licensing.”
