The Grand Leap

Causation, Prediction, and Search by Spirtes, Glymour, and Scheines (SGS) is an ambitious book. SGS claim to have methods for discovering causal relations based only on empirical data, with no need for subjectmatter knowledge. These methods—which combine graph theory, statistics and computer science—are said to allow quick, virtually automated, conversion of association to causation. The algori...

On leap Zagreb indices of graphs

The first and second Zagreb indices of a graph are equal, respectively, to the sum of squares of the vertex degrees, and the sum of the products of the degrees of pairs of adjacent vertices. We now consider analogous graph invariants, based on the second degrees of vertices (number of their second neighbors), called leap Zagreb indices. A number of their basic properties is established.

Look before you leap.

The decision to leave a job can be very stressful. Multiple variables must be considered before turning in your notice. The goal of this paper is to help you decide if changing jobs is a smart decision, and, if it is, when to do it.

Look before you leap.

Hybrid Chernoff Tau-Leap

Markovian pure jump processes model a wide range of phenomena, including chemical reactions at the molecular level, dynamics of wireless communication networks, and the spread of epidemic diseases in small populations. There exist algorithms such as Gillespie’s stochastic simulation algorithm (SSA) and Anderson’s modified next reaction method (MNRM) that simulate a single path with the exact di...
