The symmetry and non-degeneracy conditions are still kept. The particular case where the metric … monomial-ideals× 29 octave× 28 For questions about Octave, a high-level interpreted language for numerical computations. pseudoinverse× 28 The operator $A^+$ which best approximates a solution to linear equations $Ax+b=0$ even if $A$ is singular. cellular-automata× 28 constraint-programming× 28 a particular form of optimization modeling that tends to be well-suited for combinatorial models like scheduling and planning. distribution-tails× 28
