When dealing with real-world optimization problems, decision-makers usually face high levels of uncertainty associated partial information, unknown parameters, or complex relationships between these and the problem decision variables. In this work, we develop a novel Chance Constraint Learning (CCL) methodology focus on mixed-integer linear problems which combines ideas from chance constraint l...

For a binary integer program (IP) \(\max c^\mathsf {T}x, Ax \le b, x \in \{0,1\}^n\), where \(A \mathbb {R}^{m \times n}\) and \(c {R}^n\) have independent Gaussian entries the right-hand side \(b {R}^m\) satisfies that its negative coordinates \(\ell _2\) norm at most n/10, we prove gap between value of linear programming relaxation IP is upper bounded by \(\text {poly}(m)(\log n)^2 / n\) with...

Maternal ratings on internalizing (INT) and externalizing (EXT) behaviors were collected in a large, population-based longitudinal sample. The numbers of participating twin pairs at ages 3, 7, 10, and 12 were 5,602, 5,115, 2,956, and 1,481, respectively. Stability in both behaviors was accounted for by genetic and shared environmental influences. The genetic contribution to stability (INT: 43%;...
