Encyclopedia > Abacus system

The abacus system of mental calculation is a system where users mentally visualize an abacus to do calculations. No physical abacus is used; only the answers are written down.


This system is being propagated in Singapore, South Korea, Thailand, Japan. Mental calculation is said to improve mental capability, increases speed of response, memory power and concentration power.


Some veteran and prolific abacus users naturally tend to not use the abacus anymore but perform calculations by visualizing the abacus. This was verified when the right brain measured heightened EEG activity when calculating and compared with non-veterans who were using the abacus to perform calculations.

ABACUS - A Branch-And-CUt System (202 words)
ABACUS is a software system written in C++ that provides a framework for the implementation of branch-and-bound algorithms using linear programming relaxations.
ABACUS allows the software developer to concentrate merely on the problem specific parts, i.e., the separation of cutting planes, column generation, and primal heuristics.
ABACUS supports the Open Solver Interface (Osi) developed by the COIN-OR (COmputational INfrastructure for Operations Research) project which means that every solver supported by OSI can be used to solve the relaxations.
