𝐔𝐧𝐨𝐒𝐨𝐥𝐯𝐞𝐫.𝐣𝐥 now a registered Julia package 🥳
Uno is a highly customizable #SQP and #barrier solver for nonlinearly constrained optimization. It can mimic #filterSQP (SQP method) and #IPOPT (barrier method)

My nonconvex #optimization solver Uno (#SQP + #barrier) has reached floor(100𝝿) ⭐ on Github
Assembles building blocks (such as computation of descent directions and globalization techniques) effortlessly
