The point and figure chart analysis was in vogue much before computers were invented. Point and figure charts can be better understood by comparing them with bar charts. A bar chart is a combination ...

The statistical physics of graphs and partition functions represents a vibrant intersection of graph theory, statistical mechanics and computational complexity. By summing over an ensemble of ...

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) ...

In this paper the generating function for the numbers of variations with repetitions and a certain type of restrictions is determined. The variations in question are connected with paths in ...

Functions are the structured or procedural programming way of organizing the logic in your programs. Large blocks of code can be neatly segregated into manageable chunks, and space is saved by putting ...
