Rag-stone
Rag-stone is a name given by some architectural writers to work done with stones that are quarried in thin pieces, such as Horsham Stone, sandstone, Yorkshire stone, and the slate stones, but this is more properly flag or slab work. Near London, "rag-stone" often means Kentish ragstone, a material from the neighbourhood of Maidstone. Rag-stone is peculiarly suited for medieval work. It is often laid as uncoursed work, or random work, sometimes as random coursed work and sometimes as regular ashlar. Ragstone, a dull grey stone, is still quarried on an industrial scale close to the Kent Downs AONB. It has traditionally been used within the AONB as a road stone, cobble or sett and a walling block. Although difficult to 'dress' with a regular face, it has been used as rectangular blocks for the construction of walls and buildings and was very popular for the construction of 19th-century churches. More frequently, owing to the difficult and variable nature of the stone, it is see ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

In turn-based games, permanent brain (also called pondering) is the act of thinking during the opponent's turn. Chess engines that continue calculating even when it is not their turn to play end up choosing moves that are stronger than if they are barred from calculating on their opponent's turn. Use with chess programs The strength of chess programs depends very much on the amount of time allocated for calculating. Many chess programs use pondering to improve their strength. Current programs cannot create strategic plans, so a program simply tries to predict the opponent's move and begins to calculate its response. If the opponent's move has been guessed correctly, then the program continues to calculate. If the prediction fails, the program begins a new computation. Pondering is less effective than normal thinking. For example, if the program guesses 25% of the opponent's moves correctly, the use of pondering is on average equivalent to increasing the normal calculating time ...
