Killer Sudoku (also called Sums Sudoku, Sums Number Place, Samunamupure, Kikagaku Nampure) is a puzzle that combines elements of Sudoku and Kakuro.Despite the name, the simpler killer sudokus can be easier to solve than regular sudokus, depending on the solver's skill at mental arithmetic, the hardest ones, however, can take hours to crack.In Killer Sudoku, sub-regions have specified sums, and no number can be repeated within a region.

Straights is a logic puzzle.It is a grid, partially divided by black cells into compartments.Each compartment, vertically or horizontally, must contain a straight - a set of consecutive numbers, but in any order (for example: 2-1-3-4).The aim is to fill all white cells with the numbers from 1 to N (where N is the size of the grid).No single number can repeat in any row or column.Clues in black cells remove that number as an option in that row and column, and are not part of any straight.

Binary puzzle (also known as "Binairo", "Takuzu", "Tohu wa Vohu") is a logic puzzle that you can solve by using only zeros and ones. The rectangular or square grid should fill the numbers in accordance with the following rules: - Each row and each column contain the same number of digits "1" as digits "0" (or one more for odd sized grids). - The same number can only be in no more than two cells in a row. - Each line must be unique, and each column must be unique. In the book you will find a description and examples of solutions for all puzzles.The book is for those who like logic and math problems. Decide, developing and improving.

Suguru (also known as "Number Blocks") is a logic puzzle that has simple rules, but which provides sufficient challenges to satisfy the most enthusiastic solvers!The task consists of a rectangular or square grid divided into regions.Each region must be filled with each of the digits from 1 to the number of cells in the region.Cells with the same digits must not be orthogonally or diagonally adjacent.Even though the rules are simple, you will need all your skills to solve it.

Hidoku (from Hebrew: "my puzzle") is a logical puzzle.The goal of Hidoku is to fill the grid with consecutive numbers that connect horizontally, vertically, or diagonally.In every Hidoku puzzle the smallest and the highest number are presented in the grid. There are more numbers on the board to help to direct the player how to start the solution and to ensure that Hidoku has only a single solution.Hidoku puzzles are similar to Numbrix. The most important difference is that diagonal moves are allowed.

Numbricks - kind of logic puzzle. It is a rectangular grid in which some cells are numbers. Required to fill the empty cells so that all the numbers have been connected in series horizontally or vertically. Moving diagonally is not allowed.

Sudoku Jigsaw (also known as "Irregular", "Nonomino" or "Geometric Sudoku") is a logic-based, combinatorial number-placement puzzle.Jigsaw Sudokus are very similar to regular Sudoku puzzles. Regular 8x8 Sudoku that row and column rules apply, but instead of a 4x2 grid they are nime Jigsaw shapes.Each row, column and jigsaw shape contains all of the digits 1 through 8. In all other respects the puzzle works in the same way, but this change in the region shapes introduces new twists into the logic required to solve the puzzle - and often makes it much harder for you to find the next move as a result!Every Jigsaw Sudoku puzzle only ever has one possible solution, and it can always be reached via reasonable logical deduction. In other words, guessing is never required.

Sudoku X also called Diagonal Sudoku.The puzzle is a 6x6 grid made up of 3x2 subgrids (called "regions").Some cells already contain numbers, known as "givens".The goal is to fill in the empty cells, one number in each, so that each column, row, region and diagonal contains the numbers 1 through 6 exactly once.Each number in the solution therefore occurs only once in each of three "directions", hence the "single numbers" implied by the puzzle's name.

The world is moving away from demand-driven electricity markets supplied by centralized generation and distribution of fossil-fuel-produced electricity. Increasing reliance on weather-dependent renewable sources will require a shift toward a supply-driven paradigm, while beneficial electrification, including widespread adoption of electric vehicles, heat pumps, and batteries will offer considerable but widely distributed demand flexibility that can be used to compensate for supply variability. The open-source Power Trading Agent Competition (Power TAC) platform simulates a decentralized future, modeling the high complexity of future retail electricity markets. This book describes a variety of approaches to profitable trading in realistic wholesale and retail electricity markets. It presents actionable insights from extensive exploration of policies and business models for retail electricity markets gained from a decade of Power TAC tournaments, and from research inspired by the Power TAC experience. Featuring contributions from tournament designers, competitors, and scientists combining best practices from computer science and economics and management science, this book is of benefit to academics, researchers, practitioners and policy makers in sustainable energy and wholesale and retail electricity markets.
