r648 r743 30 30 sequence numbers which would change basis. Sequence numbers are 0..numberColumns 31 31 and numberColumns.. for artificials/slacks. 32 For nonbasic variables the sequence number will be that of the nonbasic variables. 32 For nonbasic variables the information is trivial to compute and the change in cost is just minus the 33 reduced cost and the sequence number will be that of the nonbasic variables. 34 For basic variables a ratio test is between the reduced costs for nonbasic variables 35 and the row of the tableau corresponding to the basic variable. 36 The increase/decrease value is always >= 0.0 33 37 34 Up to user to provide correct length arrays. 38 Up to user to provide correct length arrays where each array is of length numberCheck. 39 which contains list of variables for which information is desired. All other 40 arrays will be filled in by function. If fifth entry in which is variable 7 then fifth entry in output arrays 41 will information for variable 7. 35 42 36 43 When here  guaranteed optimal … … 45 52 For basic variables the sequence number will be that of the basic variables. 46 53 47 Up to user to providen correct length arrays. 54 Up to user to provide correct length arrays where each array is of length numberCheck. 55 which contains list of variables for which information is desired. All other 56 arrays will be filled in by function. If fifth entry in which is variable 7 then fifth entry in output arrays 57 will information for variable 7. 48 58 49 59 When here  guaranteed optimal
