Function simplifyCore #

simplifyCore() performs single pass simplification suitable for applications requiring ultimate performance. To roughly summarize, it handles cases along the lines of simplifyConstant() but where knowledge of a single argument is sufficient to determine the value. In contrast, simplify() extends simplifyCore() with additional passes to provide deeper simplification (such as gathering like terms).

Specifically, simplifyCore:

• Converts all function calls with operator equivalents to their operator forms.
• Removes operators or function calls that are guaranteed to have no effect (such as unary ‘+’).
• Removes double unary ‘-‘, ‘~’, and ‘not’
• Eliminates addition/subtraction of 0 and multiplication/division/powers by 1 or 0.
• Converts addition of a negation into subtraction.
• Eliminates logical operations with constant true or false leading arguments.
• Puts constants on the left of a product, if multiplication is considered commutative by the options (which is the default)

math.simplifyCore(f)                          // Node "2 * x"
math.simplify('2 * 1 * x ^ (1 - 0)', [math.simplifyCore]) // Node "2 * x"
