    What is the meaning of the sigma notation in this matrix A?

    The author referenced an article where I assume he got this definition. A 1956 article by F.H. Lesh; and the notation was no different (aside from the swapping of several letters). That said, I shall search around the world wide web for further definitions to see if any enlightenment is...

    What is the meaning of the sigma notation in this matrix A?

    The Matrix is of variable dimension, the author chose the letter 'o' to signify 'order' and so the matrix is o-by-o, depending on what 'o' is. I've taken this from the appendix of "Generalizing Surrogate-assisted Evolutionary Computation", by Lim et al. It's within the authors description of...

    What is the meaning of the sigma notation in this matrix A?

    Thanks for the quick response. Earlier in that section of the report it in fact defines x_i (where i = 1,2... m)to be a vector from a set of vectors (set size m), rather than a component of the vector x. It then defines that a second subscript (i.e. x_i_j) indicates the vector component of...

    What is the meaning of the sigma notation in this matrix A?

    I've been clawing at my mind for a while regarding this, I pray somebody can help me. I was implementing a method from a computer science paper when I came across this: [PLAIN]http://www.mattkent.eu/challenge.png Bearing in mind that x is a vector, epsilon is a vector of integers (and...
