We used cylindrical algebraic decomposition to solve the system of polynomial inequalities.
我们使用圆柱代数分解来求解这组多项式不等式系统。
In real quantifier elimination, cylindrical algebraic decomposition constructs a cell decomposition where each polynomial has invariant sign on every cell.
在实数域的量词消去中,圆柱代数分解会构造一种单元分解,使得每个多项式在每个单元上符号保持不变。
