WebProjections 5 In the more general case, we can define the projection onto Ω: ∏ = argmin 7∈8 7− In this case, ∏[] is again the “closest” point in Ω to . This projection operator is well-defined only for certain types of constraint sets: for example, closed convex sets. For some sets Ω, the “arg min” above is not well-defined.
