What this calculator teaches
Estimate the number of comparisons needed by binary search on a sorted list.
Graph theory and algorithm mathematics are core parts of discrete math and computer science. They help explain networks, dependency graphs, search, optimization, data structures, and route planning.
Formula & Symbols
| Concept | Formula or rule |
|---|---|
| Worst-case comparisons | ceil(log2(n + 1)) |
| Binary search idea | Each comparison cuts the remaining search interval roughly in half |
Worked Example
- For 1000 items, binary search needs about 10 comparisons in the worst case.
- Click Calculate to see the result and the algorithm steps.
- Change one edge, node, or weight and compare how the output changes.
When to use it
Common mistakes
Use arrows like A>B when direction matters. Use A-B when the edge should work both ways.
Weighted algorithms need entries such as A-B:5. If no weight is supplied, the calculator treats the edge weight as 1.
Some graph problems grow quickly. Hamiltonian path and similar searches are meant for small educational graphs.
