# Solvers  &  Fuzzy Logic

--- Table  of  Pages ---

Are you ready to get serious?  This page will get you from newbie status to judo expert in the shortest time possible.  BloodHound is a powerful animal, and you’ll want to bite into these juicy vids where we show you the advanced stuff.

## In Depth Videos

Here are some Training Workshop videos teaching how to use each Solver in detail. *(You may want to skip the first 10-15min introduction for the rest of the workshops)

Each of these videos should be watched in Full Screen mode to see all details.  Start the video and then click the YouTube logo or the Full Screen icon, at the bottom right, to expand the video size.

### Principles of How Solvers Work

This Workshop covers the fundamental workings of how BloodHound solvers calculate their output.  It will be good to have a basic understanding of what solvers are doing under the hood so to speak.

### What is Fuzzy Logic

BloodHound is built on fuzzy logic, and all Solvers use it.  Learn the fundamentals of what fuzzy logic is.

### How to Nest Indicators Within a Solver

Nesting indicators is feeding the output of an indicator into the Input Series of another indicator.  E.G.  If you want to apply an SMA smoothing to the Momentum indicator on your chart, you would open the Indicator window and change the Momentum's Input Series to the SMA indicator.  This can be done in BloodHound as well.
