Logic puzzle might be present in lieu of a grid in a puzzle about the location of different shops. Logic puzzle A logic puzzle is a puzzle deriving from the mathematics field of deduction. The logic puzzle was first produced by Charles Lutwidge Dodgson, who is better known under his pen name Lewis Carroll, the author of "Alice's Adventures in Wonderland". In his book "The Game of Logic" he introduced a game to solve problems such as confirming the conclusion "Some greyhounds are not fat" from the statements "No fat creatures run well" and "Some greyhounds run well".

Combinational logic a product of sums. Consider the following truth table: Using sum of products, all logical statements which yield true results are summed, giving the result: Using Boolean algebra, the result simplifies to the following equivalent of the truth table: Minimization (simplification) of combinational logic formulas is done using the following rules based on the laws of Boolean algebra: With the use of minimization (sometimes called logic optimization), a simplified logical function or circuit may be arrived upon, and the logic combinational circuit becomes smaller, and easier to analyse, use, or build. Combinational logic In digital circuit theory, combinational logic (sometimes
