Declare your variables using =CSP_INT(range, min, max) or
=CSP_DOMAIN(range, domain_range)
anywhere in the sheet.
Add boolean constraints like =A4>1, =OR(A1=1, B1=1), or
=SUM(R1:R3)=3 anywhere else. Use =DIFFERENT(range) for a constraint that values in the
range are pairwise different. Supported operators/functions: AND, OR, SUM,
ABS, NOT, =, <, >, <>,
<=, >=.
The solver needs access to the spreadsheet - made it publicly writeable or add
